The Star Gate of Sri Lanka

The Star Gate of Sri Lanka - Sakwala Chakraya might be a key to global system of "SCIROCCO" Infrasound vibroacoustic broadcasting interfaces.  

First of all I want to express my thanks to my friends from Sri Lanka, who inspired me 
to write this article and provided me with really unique ideas and materials:

Introduction.

There is an amazing and unexplained artifact of an ancient civilization of Sri Lanka carved on the rock in Ranmasu Uyana (Gold Fish Park), which is located in the ancient city of Anuradhapura. This artifact is called Sakwala Chakraya, also known as The Star Gate of Sri Lanka. It is sandwiched between the Thissa Wewa reservoir and the Isurumuniya Rock Temple.  All of them are forming the pleasure garden of the ancient Sri Lanka royals, full of secrets still unexplained by modern knowledge. It is possibly one of the most hidden mysteries of Human civilization.
The goal of this article is attempt to solve a riddle of Sakwala Chakraya.

Sakwala Chakraya appears to be a carving on the surface of a granite rock as some kind of a "weird circular diagram". It's cut shallowly on the steeply projecting rock face and looks like a great chakra, or circle 6 ft in diameter. On it there are rectangular divisions that contain figures  (mostly small circles with cross inside), the whole girt, as a tyred wheel, by a band on which is displayed variant piscine and crustacean life swimming in a circle from right to left.

Sakwala Chakraya (Star Gates) is located just beyond the northern confines of Isurumuniya Rock Temple, at the very foot of the embankment of the Tisa Wewa tank, this place is also known as RANMASU UYANA, which means the garden of golden fishes. There are lots of ponds like in Sigiriya.

The first and a very good one scientific description of this you can find in the "Archaeological Survey of Ceylon North-Central and Central Provinces, Annual Report", written in 1901 by H. C. P. Bell C.C.S., Archaeological Commissioner. Here is a link to PDF.

Meaning of the name.

For a start, let's investigate a meaning of a phrase "Sakwala Chakraya". 

Sakwala:

• This is a bana or "word" uttered by Gautama Buddha in his oral instructions. Sakwala is a mundane, or rather a solar system, of which there is an infinite number in the universe, and which denotes that space to which the light of every sun extends. Each Sakwala contains earth, hells and heavens (meaning good and bad spheres, our earth being considered as hell, in Occultism); attains its prime, then falls into decay and is finally destroyed at regularly recurring periods, in virtue of one immutable law.
• Direct Sinhala meaning of Sakwala is Universe, or Galaxy. 

Chakra: 

• It is a Sanskrit term meaning wheel or disc. 
• Also Chakraya means disc, or rotating circle on Sinhala. 
• From Buddhist point of view this is a structure of Universe or rotation cycle of life forms.

So, the meaning of phrase "Sakwala Chakraya" might be "The rotating cycle of (life in) the Universe". 

But please don’t forget that we have no idea about when and by whom this phrase was originated from the very outset. May be, in ancient times it had another Name. It is because some things in Anuradhapura ancient city may be much older than Buddhism itself… 

An interesting observation: One of my Lankan friends said: "Archaeologists didn't mention about dates of Sakwala Chakraya and Ranmasu Yana (where are a lot of magnificent granite ponds like in Sigiriya) origin... Because it's a puzzle to the archaeologists in Sri Lanka. Even NASA people had observed them in early 90's including Sigiriya. So they also keep their eyes on these two places." 

My comment: And it's not possible to measure the carbon dates, because this method could be used only for organic materials (materials of biological origin). 

Let's look at this riddle from the different angle, trying to understand it in the other way, different from officially accepted versions and theories.

Investigation of current versions of purpose.

There are some versions what the Sakwala Chakraya actually is:

1. According to the official version, described in the above-mentioned "…Annual Report", Sakwala Chakraya is an ancient "map of the world" - perhaps the oldest in existence. The concentric circles with their interspaces at the centre of the chakra can assuredly mean only the Sakvala, in the centre of which rises Maha Meru or Sri Yantra ("sacred instrument"), surrounded by the seven seas (Sidanta) and walls of rock (Yugandhara) which shut in that fabulous mountain, 1,680,000 miles in height, half below, half above, the ocean's surface. Sun and moon (in the second strips) lie on either side of the Sakvala: round about in space are scattered innumerable other worlds represented by quadrisected circles. Below and around is the "world of waters" (i.e., the circular band) in which swarm gigantic uncouth denizens-fish, turtle, crab, and other marine fauna.

From the other hand, it is also the way Tantric Buddhist monks perceived the world. So, Sakwala Chakraya could be used for Buddhist meditation.

Four Buddhist monks are meditating in front of Sakwala
Chakraya, sitting on stone sits

So, can Sakwala Chakraya originally be a "map of the world" as it was presumed by Hinduism or Buddhism? I think it is hardly possible.

I have some arguments based on many facts for that:

1.1. Sakwala Chakraya is completely different from Sri Chakra with Maha Meru, as you can see with your own eyes:

Sri Chakra ("sacred wheel") or Mahameru

3D model of Sri Chakra  - Sri Yantra ("sacred instrument").
The two dimensional Sri Chakra, when it is projected into
three dimensions is called a Maha Meru.

So, as you can see, Sakwala Chakraya represented differently – with neatly drawn rectangular areas, in some way logically symmetrical by horizontal line. Image consists of standardized elements – two sets of seven concentric circles with dots (cups) in center, rectangular areas similar to each other and circles with cross inside. Rectangular areas are drawn by orthogonally curved straight lines. Central set of circles is exactly in two times bigger in diameter than upper set of circles. There are only some of elements look strange, but we will talk about it later. 

Sri Chakra is drawn by inserted in circles triangles of different sizes, in turn inserted into each other with some displacement from the mutual center of symmetry:

By the way, here is a very interesting article about How to Draw the Sri Chakra Yantra.

If we are looking for similarity, we can find it here with a high probability:

The Star of David, known in Hebrew as the Shield of David or Magen David, generally recognized as a symbol of Jewish identity and Judaism.
But it was not a symbol of Judaism in ancient times. Initially it is an ancient Hindu symbol, called Anahata Chakra, Heart Chakra of love.
There is really something to think about...

1.2. Mark of a cross inside a circle (which we see many on Sakwala Chakraya) has some similarity with so-called Sun Cross or "wheel cross"  which is frequently found in the symbolism of prehistoric cultures, particularly during the Neolithic to Bronze Age periods (presumably 7000 BC–3000 BC). It could not have any direct connections with Buddhism or Hinduism.
There are a lot of these symbols carved on the stone roofs of the Dolmens of North Caucasus. 

These terms "sun cross" and "wheel cross" are modern and hint at speculative interpretations in the context of prehistoric religion. The actual significance of these symbols in the prehistoric period is not known. 

An interesting detail: it is also an astrological symbol of the Planet Earth.

So, it is obvious that originally Sakwala Chakraya didn’t represent any religious aspects and couldn’t be used as an artifact of any known to us religions. 

1.3. There are no other known images similar to Sakwala Chakraya in Hindu or Buddhism culture.

1.4. There are no other known ancient images similar to Sakwala Chakraya in the World at all, except of some masterpieces of prehistoric art. We will speak about it later. 

2. At later stages the historians have interpreted Sakwala Chakraya as descriptions of animal evolution, from the point of view of an ancient people. 

Assumption: it cannot be description of evolution, because of following facts:

2.1. There are inhabitants of a sea only represented on the outer circle of Sakwala Chakraya. There are no inhabitants of terrestrial ecosystem. No human kind. 

2.2. There are some unknown creatures are shown among sea inhabitants. One of them might be recognized as a mermaid.  Some of them could hardly be recognized at all. 

Conclusion: Sea creatures were placed on the image in purpose to show that it had destination concerned with the sea (ocean) scope. What kind of destination we will examine later. 

An interesting detail: In Hindu Mahabharata epic god Indra gives a powerful weapon to Arjuna, with task to destroy a race of Nivatakavachas – mighty creatures living deep under the oceans. Nivatakavachas are glorious and legendary beings extremely powerful in magic, in spite of their evil to human beings. Even the Devas under Indra command cannot overcome them. 

In the Ramayana, Nivatakavachas strike an alliance with Ravana, after Ravana is unable to defeat them.

Finally Nivatakavachas were defeated and destroyed by Arjuna. The Nivatakavachas magic mermaids sank into oblivion and become legends and myths…

3. This is a floor plan of Anuradhapura, or Sigiriya (a rock garden found close to Anuradhapura), or Sri Lanka. 

I would say that this is a very logical version. I would tell more, that it might be a floor plan of some part of the land surrounded by water – for example, Island of Sri Lanka, or even complex of something, scattered all around the Globe.

Thus, Ivan Sanderson mapped twelve areas on the Earth with abnormal electromagnetic aberrations shown by the map above, which reminds in some way shown on Sakwala Chakraya circles with cross inside. 

4. The most incredible version says that Sakwala Chakraya is a reference designation of real Star Gates (teleport), which was placed in Anuradhapura and used by extraterrestrials for visiting Earth. So, this carving may contain a secret key to space travelling via portal with using some kind of teleporting technology. 

Comment: it is very fantastic version and we cannot take it seriously into consideration, but I would not totally refuse it from the start until the opposite is not proved. Different versions might not always have a mutual exclusion…  

The discovery of the Sri Lanka Stargate marking had created waves amidst archeologists and pre-historic investigators, some drawing parallels between the Stargate charts found in Abu Ghurab in Egypt and "The gate way to the gods" in Peru. The bizarre coincidence of all the three marks been found in the vicinity of a water way, with sophisticated engineering methods, had given rise to various theories.

La Puerta de Hayu Marka or The Gateway to The Gods
in Peru close to Lake Titicaca. 

A huge mysterious door-like structure has recently been discovered in September 1996 in the Hayu Marca mountain region of Southern Peru. Placed in 35 kilometers from the city of Puno it has long been revered by local indians as the "City of the Gods", and has never been fully explored because of the rugged mountain terrain.

Abu Ghurab Stargate is a part of the Abu Sir Pyramid complex.

About 20 minutes drive from the Great Pyramid, and visible from the Giza Plateau on clear day, is one of Egypt’s greatest treasures from antiquity, and one of the most extraordinary places on our planet.

Abu Ghurab, or "the crow’s nest" as it is called, is a closed to the public archaeological site in the pyramid fields that run alongside the Nile south of Cairo.
Egyptologists quaintly refer to it as a "sun temple", a "burial center" or "funerary complex" for a new cult of Ra (they usually use these terms when the actual function of a place is unclear).  You can read an interesting article about it here. 

The most favorite is the claim that these Stargates were used by extraterrestrials that were gold mining in Earth. Their theory is built up on the fact that in 2400 BC the Stargate in Abu Ghurab Egypt was surrounded by water while "La Puerta de Hayu Marka" Or "The Gateway to The Gods" in Peru too is built closer Lake Titicaca, with underground water tunnels and chambers beneath the pyramids, so does Sakwala Chakraya on the shore of Tissa Wewa water tank in Anuradhapura. 

The advocates of the "processing gold from the waters of Earth" theory believes that these water channels, chambers, reservoirs and filters found near each Stargate to have been a part of a sophisticated mechanism developed by extraterrestrials thousands of years ago.

If the theory is held to be true, Ranmasu Uyana had once been a "gold processing center of extraterrestrials", which arrived on earth through Stargates.

Yet archeologists are eager to discard these theories as pure imagination. 

Conclusion: So, until there are no proven evidences for Stargate theory, we will not take it into consideration. 

5. Some people believe that it's a secret message from aliens or gods. As for the described above Stargate theory I would not take it into consideration until we have proven evidences of this. In the same time, there is something to think about. 

Theory of Ancient Aliens, related to the location of Sakwala Chakraya (to be exact the ancient Anuradhapura city), has a place in modern scientific society. 

Thus, according to discovery made in 1996 by researcher and historian Mihindukulasuriya Susantha Fernando, there exists a perfect alignment of the three main stupas - Mirisavatiya, Ruvanweli (Ruwanwelisaya) and Jetavana (Jetavanaramaya) at Anuradhapura, with three stars in the constellation of Orion, namely Rigel, Alnitak and Bellatrix.

The Orion constellation with the labels of the major stars 

That means that the three sides of the triangle in the ground layout of the three stupas, built between 161 B.C. and A.D. 331, are correlated precisely with the three sides of the triangle of three stars on the right-hand wing of the constellation of Orion. It is a kind of heaven-ground duplicity. 

Fernando's discovery was described in his 1997 book "Alien Mysteries in Sri Lanka and Egypt". 

It was also proven in book "Heaven's Mirror", researched and written by two British scholars, Graham Hancock and Santha Faiia , which was published in 1998 by the Penguin Group in London.  Here you can read a short brief of this on Official Website of the Sunday Times Newspaper in Sri Lanka. 

6. Here is my own version of what the Sakwala Chakraya actually is. As an engineer, I would rather say that Sakwala Chakraya is some kind of working drawing - most likely floor plan or (and) technical scheme of something with technical purpose without any doubts, because of standardized elements and graphic principles of its drawings. Here we can see some examples of this similarity:

Drawing of The Phillips Exeter Academy Library
in Exeter, New Hampshire, U.S. 

Floor plan of the NE corner of the Parthenon 

In other words, it is more likely a floor plan or scheme (drawing) of some kind of device or hardware complex. Device or complex itself could be by the size of a town, or by the size of an Island. Why not? Also I'd say, that similarity of some elements of the complex tells us about the fact, that complex itself is composed of similar hardware parts.

After all I would say that different versions (theories) not necessarily have mutual exclusion to one another, they could be mutually complementary.

So, let's investigate my own version of this possible use, looking at this from the top of modern knowledge and technologies. Even if this not let us to solve a riddle, we would be able to move closer to it.

Technical analyze of Sakwala Chakraya. 

First of all I draw your attention to the strict similarities between symbols of Sakwala Chakraya, Great Pyramid and reference designation of radio components related to oscillatory processes and radio communication.

Here I consider necessary to make some digression and familiarize you with latest investigations in the field of ancient acoustic technologies related to infrasound use.

Recently in Russia and Ukraine started a quite new researching project, accomplishing by group of enthusiasts under the direction of radio engineer Vladimir Yashkardin - open research project SCIROCCO.

The goal of this project is description of real purpose of building pyramids by ancient civilizations and functioning of pyramids and thousands of different mysterious megalithic objects from the point of view of Wave Theory and theoretical foundations of Radio Engineering (TRE). 

By my opinion, it is the most logical, consecutive and comprehensive theory for the present time: Project SCIROCCO. Infrasound vibroacoustic broadcasting interface (on English). 
Short version of the article is here: What for the pyramids were built? How the pyramids work? Here is explained (in short) true purpose of the Egyptian and other pyramids.
I strongly recommend reading it very carefully in spite of some possible difficulties with understanding. 

In short, pyramids of Giza Plateau are very powerful vibroacoustic infrasound oscillators/transmitters. The main purpose of these structures is the information broadcast over land and water over long distances, may be around the whole Globe. Pyramid of Cheops could generate 7 different frequencies: 9.2-10.3-10.9-12.25-13.75-15.4-16.35 Hz (recall seven concentric circles on Sakwala Chakraya) and ensure transmission of audio and video information.

(physical scheme of a vibroacoustic generator).

All elements of the generator, which work with acoustic energy, made of granite:

1. Resonator (tuning fork).

2. Active chamber of resonant amplifier.

3. Focusing corner reflector.

4. Feeder channel of the positive potential energy.

5. Feeder channel of the negative potential energy.

6. Granite plate (membrane) of the positive potential of wind energy.

7. Granite plate (membrane) of the negative potential of wind energy.

8. Signal tap (waveguide) from the amplifier output to the positive feedback loop.

9. The switch of the positive feedback.

10. Channel (waveguide) of positive feedback.

11. Wave channel (waveguide).

12. Resonant vibrator.

13. Matching devices.

- Energy source: wind flow (constantly blowing southern wind "Scirocco")

So, we will investigate main but difficultly explainable symbols of the Star Gates:

1. Meaning of two sets of seven concentric circles with dots (cups) in center.

Central element of Sakwala Chakraya. 

It can hardly be a picture of our Solar System, because it has seven circles only. The Solar System comprises Sun and eight planets (there used to be more), asteroids and some protoplanets (dwarf planets).

With high possibility it can symbolize some kind of an oscillation process, radiation from antenna (acoustic radiation). 

Oscillation process on the water surface due to falling drops. 

Symbol of electromagnetic oscillation process –
radio masts with radio waves. 

So, ancient builders were familiarized with oscillation process very well, we will see more evidences of it later.

2. This symbol is very similar to axonometric drawing of one of Pyramids of Giza Plateau:

Symbol of pyramid on Sakwala Chakraya,
axonometric drawing, with some underground
tunnels

Diagram of the pyramid of Cheops (Great Pyramid) 3D-model

3. Symbol of wave on Sakwala Chakraya is very similar to the comb above the main entrance to the Great Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops). This is very important part of transmitter – switch of positive feedback, in short, switch of transmitter. 

Wavy symbol of "comb" on the Sakwala Chakraya.

Sanskrit inscription on the comb above the main entrance
to the pyramid of Khufu .

An interesting detail: there is an article in the Web: "Resonance in Paleo-Sanskrit Inscriptions on the Great Pyramid" which says that these characters in fact are the inscription written on Sanskrit. The phrase was deciphered by Prof. Kurt Schildmann (1915-2005) as vi Sani raua ra Yoni - its translation means literally: "From masculine force, thundering, granting feminine". The interpretation of this phrase is that the infrasound (thunder) converts one basic principle (energy) into another: "Yang" into the "Yin", for example, if we consider the matter in terms of human bioenergetics. The article says that the pyramids of Giza plateau purposefully focused infrasound vibrations of the Earth for the "…global infrasonic synchronization of the collective human consciousness, thereby endowing feminine forces". 

This is a quite interesting idea which confirms the theory of infrasound broadcasting. Moreover, a detailed study of the question might help us with understanding not only the simple fact of subsonic transmission, but also the role of infrasound in the connection on human biorhythms to biorhythms of Planet Earth. Scientists have already found that the Planet Earth "sings" with very low, infrasound frequency (to be exact there is a extremely low oscillations on infrasound frequencies in so-called Van Allen radiation belts, generated by the Earth's magnetic field, which are also the reason for reason for Aurora Borealis - "northern lights"). This "singing" is also connected with the activity of the Sun. You can read about it an article in National Geographic News: Earth's Magnetic Field Hisses Due to Distant "Chorus". 

4. Umbrella symbols – from the very ancient Veda umbrella was considered as a symbol of supreme power in "God-King" conception; also umbrella was considered as abode of some "guardian angel", which helped to King and can interfere in the doings, providing protection for the interests of King's Dynasty.

So, from the modern point of view, the sign of umbrella means:

• from the one hand – symbol of supreme power; so two umbrellas means two Kings or most likely King and Queen. 
• from the other hand – communicating device (remind modern parabolic satellite antennas) for receiving advices and help from some "gods".

5 and 6 – closed and opened circuits. 

In connection with this theory more signs of Sakwala Chakraya become understandable:

Closed circuit (from the right) – transmitter is working, a tetracrepid star symbolizes directional diagram of waves transmission (from the left). Pyramids have four sides strictly oriented to the cardinal points, so, working as an antenna, it radiates maximum power by these four directions.

Example of the directional diagram of modern radio antenna

Open circuit (from the left) – there is no transmission, directional diagram is broken. 

7. Symbol of crossed circle most likely means domes – antenna resonators of domed infrasound receivers or just simply volumetric resonators of any kinds. For example, domed structures in Sri Lanka and other Asian countries – Stupas (Pagodas, or Dagabas).

What we have got in result:

Sakwala Chakraya with explanation of meaning of its symbols

1. Two oscillating processes, or two radiating sources;
2. Sign of pyramidal infrasound transmitter (may be natural mountain);
3. Sinusoid wave and "comb" with switch of positive feedback – switch of infrasound transmitter;
4. Symbol of communicating device with superiors (satellite dish) and symbol of kings power;
5. Disabled state of transmitter – open circuit, no transmission, antenna directional diagram is broken;
6. Enabled state of transmitter – close circuit, transmitter is working, a tetracrepid star symbolizes directional diagram of waves transmission from antenna;
7. Domed infrasound receivers.
8. Some unknown sea creatures, including for whom infrasound transmissions were assigned (possibly).

Thus, I assume that Sakwala Chakraya is a technical scheme which describes main principles of construction of infrasound broadcasting system.

Why it is possible?

This principle of communication is actively applied by marine animals (whales, killer whales etc.) to communicate at distances of about 1,300 km (frequency range 18...30 Hz).

The maximum distance recorded for the blue whale, was 1300 km (Miller, 1951; Scharf, 1970).

Similar systems have been developed in the 20th century for communication with moving underwater objects.

But, to achieve satisfactory results in the sound range failed.

Instead, have been developed with radio transmitters, electric range low frequency SLF (30-300Hz).

The effective size of antennas for these frequencies are thousands of miles in length (L=3*10⁸/300=1*10⁶ m = 1000 km).

These very similar communication systems are known for us today from public sources.  They are used for communication with fleet of nuclear armed submarines floating in the ocean at depths often below 300 meters. Here they are:

- "Zeus" System, Russia, 82 Hz

- "Seafarer" System, USA, 76 Hz.

It is likely that Russia and the United States could build a transmitter in the range of ELF (3-30Hz), but this information is very confidential. Cost and size of such transmitters is extremely huge.

RF signals of these frequencies can easily penetrate into the water and ice, which makes them indispensable for communication with underwater objects anywhere in the world and at any depth of the ocean. 

Now imagine how magnificent this ancient SCIROCCO broadcast infrasound system was:

1. System was able to ensure the information broadcast over land and water over long distances, at any point of the globe, all around the world, under the ground and under the water at any possible depth.
2. In essence, this is an analogue of "Zeus" (Russia) and "Seafarer" (USA) Systems, but with much better performance.
3. It is impossible to suppress such a transmission without destruction of transmitter, so the whole system has unbelievable reliability. Electronic warfare (EW) in this case makes no sense. 
4. So, you can give your orders to your battleships and other crafts with 100% reliability at any time, at any place – on the ground, or under the water and all around the globe. It is an excellent communicating system for military and non-military purpose. 

From the other hand, it one more time proves very important thing – such complexes were built by one great civilization (or Empire) scattered on the different Continents. And Island of Sri Lanka played very important role in this forgotten civilization. Was it Kingdom of King Ravana? Who knows…  

There are two sets of concentric circles (infrasound emission sources) are depicted on the Sakwala Chakraya. It means that in those times was known and used more than one transmitter, at least two. We can presume that it were Giza Pyramids and Sigiriya with Pidurangala, or sacred Mount Kailash - which is the biggest pyramidal structure on the Earth, and it seems that it still works… Not without reason it was described as a residence of Lord Siva in Hinduism and the home of the Buddha Demchok in Tantric Buddhism. 

Two times difference in diameters of concentric circles sets might mean that these two transmitters were working on two different frequencies (wavelengths), to prevent jamming of each other. 

Now, when we have carefully examined transmitter's version, it's time to draw our attention to receivers. I would say that there is hell of a lot of them all around the world, on each Continent and in every corner of the Earth. 

Classification of known infrasound receivers:

1. Data infrasound receivers:

1.1. Domed volumetric tuning-fork infrasound receivers, which could be made of bricks (stone blocks) or be carved in the rock (stone). If the antennas are made of blocks of stone, there was no need to build it on rock monolith. Such a receiver could be constructed on any ground.

Examples:

1.1.1. Stupas. In this case dome itself is working as antenna. 

The massive dome of Jetavanarama Dagaba
(Anuradhapura, Sri Lanka).

It may have originally stood over 100 m high, but today is about 70 m. This was a similar height to the Abhayagiri, with which it is sometimes confused.

When it was built it was the third-tallest monument in the world, the first two were Egyptian pyramids.

A British guidebook from the early 1900s calculated that there were enough bricks in the dagoba's brick core to make a 3m-high wall stretching from London to Edinburgh.

The Ruwanwelisaya stupa (Sri Lanka), also known as
Mahathupa, Swarnamali Chaitya, Suvarnamali Mahaceti
and Rathnamali Dagaba. 

An interesting reference: According to epic, King Dutugemunu obtained permission to build this stupa from goddess called Rathnamali. The Mahawamsa chronicle says that King Dutugemunu discussed question about its constructing with gods on some stone chairs… where it could be - in Sigiriya or Anuradhapura?!? It was the last documented contact of Man King with gods. 

Assumption: it seems that original purpose of stupas wasn’t religious. They obtained it later. Built with a lot of efforts, extremely high expenses, austere styled, without much ornamentation, they were used only for very specific technical purpose – receiving data.

1.1.2. Underground domed structures.

1.1.3. Cavity resonator with monolithic rock antennas (tumulus, dolmens, mastabas). The antenna of receiver is commonly used natural rock monolith, located in a certain direction to the infrasound transmitter. This cavity resonator has to be built on monolith; it receives data from the vibration of the monolith. 

Rocky volumetric tuning-fork receiver in Greece:

Archaeologcal site: Mine tombs of Mycenaean period -
Mazarakata

1.2. Volumetric rocky infrasound data receivers.

These receivers do not have underground domes (antennas). Usually they were built in the area where infrasound waves were concentrated on natural heterogeneity of the environment: the geological faults, rivers, mountains, mountain ranges, and were aimed at a certain angle (20-60°) to infrasound source.

1.2.1. It is believed that in Italy tumulus dome receivers were built on natural rock monoliths by Etruscans.

A dome in Ireland, this one is supposed to be
built by Celts 6000 years ago. 

The domed receivers on monolithic base at the ancient
Etruscan town near Cherveteri, Italy.
Coordinates: 42° 0'19.17"N 12° 6'10.87"E.

1.2.2. Dolmens are relatively small volumetric secondary resonators. They usually established on mountain ridges, as well as near major rivers, and in other places of natural concentration of infrasound waves.

(areas of their accumulation are highlighted)

1.2.3. Mastabas are stone trapezoid receivers, which focusing infrasound waves at some depth under its base, and were the most common transmitters of an ancient Egypt.

Vibrating from infrasound, body of mastaba sends the sound waves down (due to its trapezoid shape), focusing the sound stream deeply under its base. Unlike the spherical domes (where the focus was on the floor level), focus of mastaba trapezoid lens is under the ground. Therefore, the secondary resonator (which the official science perceives as stone tombs) was immersed in a curved shaft, so that the mine doesnt came under the focus of a infrasound beam. Placed in the focus of mastaba, secondary resonator converts infrasound in a sound wave, which comes by the air shaft to intensifying air chambers. Here you can listen to the sound, received from the pyramid, perfectly.

1.3. Tuning fork infrasound data receivers.

1.3.1. Seidhs, or Stones of Power are large stones installed on small stone supports on the solid rock base. To create a Seidh you shall select a large stone with the resonance of multiple frequency and install it on a rock correctly to the direction of the source of the incoming infrasound signal.

Typical Seidh, or Power Stone. The biggest seidh complexes
are placed in Karelia, Russia. 

Seidh by more than 2000 tons weight, installed on stone legs
which inserted in slits deeply cut in granite slope
of Sigiriya Lions Rock, Sri Lanka. 

1.3.2. Menhirs is alone standing stones installed in the natural areas of maximum concentration of infrasound signal with the resonance of multiple frequency of incoming infrasound signal. Sometimes, even fields of menhirs were installed near the major receivers along with dolmens. The Carnac Stones (France) and Stone Circle are typical examples of such complexes. There is also the Stone Ship kinds.

The Carnac stones are an exceptionally dense collection of
megalithic sites around the French village of Carnac.

1.3.3. Cromlech is a set of stones, each of which had a particular resonance with exact modulation frequency of the pyramid complex transmitter. The menhirs were mounted in a ring in the center of which was point of superposition for all transmitted frequencies.

There are images of acoustic waves radiating from vibrating 

in resonance stone cut on the Stones of Carnac

Stonehenge (Wiltshire, UK) is one of the best known examples
of cromlech in the World

I would say that most of megalithic structures in the world refer to receivers of infrasound signal.

2. Signaling infrasound receivers

Modern scholars believe these receivers are ancient seismographs, with the help of which the ancient people predicted earthquakes. This is pretty pointless, because to predict an earthquake by seismograph is impossible.

Pendulum infrasound signal receiver mechanism.

At arrival of infrasonic waves tuned on resonance frequency pendulum becomes oscillate, in its turn setting in motion the ratchet closing device of balls feeding. 

Date of origin and pre-history similarities.

So, taking into account all listed above, there is a good reason to believe that Sakwala Chakraya is a key and some kind of technical scheme which describes a principle of global infrasound broadcasting system (pre-historic global signal system) construction and work, its core elements and main purpose. The question of date of its origin is still open. 

If we look carefully to some coincidences all around the World (which may give reference to wave theory and imagery of oscillating process), we will see that there are a lot of them in Megalithic culture, to be exact in form of prehistoric art called Cup and ring marks or Cup marks. 

Cup-and-rings marks similar to radiation of waves from antenna. These are located in Northumberland, at 55.54754N 1.99632W

Petroglyph at the "Laxe das Rodas" (Stone of the Wheels),
Louro, Galicia, Spain.

Cup-and-ring mark "Petróglifo de Portaxes" at Monte Tetón,
Tomiño, the largest one in Galicia, Spain.

Such marks are found mainly in Atlantic Europe (Northern England, Scotland, Ireland, Brittany, Portugal and Galicia (North West Spain)) and Mediterranean Europe (North West Italy, Thessalia Central Greece, Switzerland). Although similar forms are also found throughout the world including Mexico, Brazil, Greece, and India.

Usually scientists refers its dating to Early Neolithic, about 10,000 to 8,500 BC (it's about 12,000 – 10,500 years ago). 

It has something in common with mythical Great Flood, which really took place about 12,000 years ago, when mean temperature on the Earth rose sharply on 8 degrees.

It would be logical to assume that the Great Flood destroyed the advanced ancient civilization, on the wreckage of which our modern revived, retaining the shards of old knowledge in the form of complicated and conflicting myths, legends and religions.

Modern archaeological finds, such as Nevali Cori and Göbekli Tepe (complex of "Stonehenges" of 50-ton stones which supposed being built more than 12000 years ago by gatherers?!?!), are changing the opinion about the level of Neolithic human civilization technologies in revolutionizing way and forced even the most conservative adherents of the generally used science to take a fresh look at the historical dating. 

Summary:

1. Sakwala Chakraya with great probability may be a key and some kind of technical scheme which describes a principle of global infrasound broadcasting system (pre-historic global signal system) construction and work, its core elements and main purpose. It can also be assumed, that infrasound broadcasting was intended for some sea inhabitants too. The question is – is there some of them now?

2. Sakwala Chakraya, along with other mystery artifacts of Sri Lanka, shows strong connection with other hardly explained artifacts all around the world, which let us assume that we have deal with remnants of one great civilization, scattered all around the World – on every Continent. 

3. Ancient knowledge of wave theory, theoretical foundations of Radio Engineering and their technologies were so excellent that let them build such great infrasound transmitters as Giza Pyramids. We can't do it today, with our modern technologies. It one more time proves the fact that this pre-civilization was more advanced than ours. 

4. Sri Lanka played important role in this great pre-civilization, about which we can judge by Sakwala Chakraya itself and lots of high-tech granite stone artifacts with evidences of machining. 

5. This great pre-historic civilization possibly could be destroyed by the Great Flood about 12,000 years ago. So, artifacts such Sakwala Chakraya and Giza Pyramids should be some older. 

6. Remnants of destroyed civilization were trying to preserve their knowledge, which was reflected in megalithic and prehistoric arts, many myths, religions and philosophy doctrines. Some of them could be successful in this, so they could use some technologies of old during long time. Such knowledge means power, so we may assume some wars took place for possession of this knowledge and technologies.

7. We shall not forget about "gods" which (according to myths and epics) were playing their own role in creation of many mysterious sites and objects, and could be aliens as well as remnants of fallen advanced civilization.

8. Described above Infrasound broadcasting system was not necessarily used for data transmission only, it could also be used for transmission of the energy (necessary for the operation of any device), as well as other purposes (e.g., to make an impact on the human body), which we will have to figure out in future.
