map of Atlantis according to blavatsky theosophy blue[From Cayce Reading 364-3]:
Yes, we have the subject [The Lost Continent of Atlantis] and those conditions. As has been said, much data has been received from time to time through psychic forces as respecting conditions in or through the period, or ages, of this continent's existence. That the continent existed is being proven as a fact.

The position as the continent Atlantis occupied, is that as between the Gulf of Mexico on the one hand - and the Mediterranean upon the other. Evidences of this lost civilization are to be found in the Pyrenees and Morocco on the one hand, British Honduras, Yucatan and America upon the other. There are some protruding portions within this that must have at one time or another been a portion of this great continent. The British West Indies or the Bahamas, and a portion of same that may be seen in the present - if the geological survey would be made in some of these - especially, or notably, in Bimini and in the Gulf Stream through this vicinity, these may be even yet determined.

                    —Edgar Cayce Reading 364-3

One of the most fascinating sets of readings Edgar Cayce ever did was about Atlantis, its discovery, history and destruction. He prophesied that a new land would appear in 1968/9 off the east coast of North America, the so-called “rising of Atlantis. It was in fact during that time that the “Bimini Road” was discovered in the Atlantic Ocean. After all these years the issue is still being debated by archeologists and scientists, but the verdict is not out yet so it may very well be.

Edgar Cayce maintained that Atlantis was the “first” civilization which was technologically superior to even our own and that its last surviving islands have disappeared somewhere in the Atlantic ocean some ten thousand years ago. Cayce revealed that the size of Atlantis was equal to that of Europe, including Asia in Europe. He saw visions of this continent of the past which had gone through three major periods of division; the first two occurred around 15,600 B.C., when the mainland was divided into islands. The three main islands of Atlantis Cayce named were Poseida, Og and Aryan.

He claimed that the Atlanteans were well versed in technology that harnessed the power of the quantum world; this included the use of crystals and sound waves for healing, elevators and connecting tunnels that operated by compressed air and steam, quartz crystal science that was used to mine gold, copper and silver from the earth. Atlanteans were adept at the use of silicon chips at levels unrivaled in the modern world. The Crystal Skull, for example, was cut with such infinite precision that “no known modern tool could have replicated the job.” They were familiar with the amplification power of crystals in laser technology and memory chips. They made extensive use of mass mental telepathy, psycho-kinesis and astral projection into fourth dimensional consciousness.

Edgar Cayce said the people of Atlantis had constructed giant laser-like crystals for power plants, and that these were responsible for the second destruction of the land. Cayce blamed the final destruction of Atlantis and the disintegration of their culture on greed and lust. According to Cayce, two rival parties fought for control of the Atlanteans in its final days. The Children of the Law of One wanted to return to a spiritual stewardship of the land based on natural laws. The other group, the Sons of Belial, wanted to exploit natural resources for material gain.

The chief focus of their conflict was a third class of dull, half-awake sub-humans used by the Sons of Belial for slave labor. The Children of the Law of One wanted to enlighten these sub–beings by raising their consciousness; the Sons of Belial wanted to keep them in ignorance and exploit them for their own gain.

But before the legendary land disappeared under the waves, Cayce revealed that there was an exodus of many Atlanteans to ancient Egypt. He attributed the Biblical Great Flood of Noah to be a result of the sinking of the last huge remnants of Atlantis. He also revealed that the many Atlanteans that managed to escape, in hope to preserve a record of their civilization created two separate archives with all their history and accomplishments so that it could be preserved for posterity. One of these archives was revealed to be buried under one of the Sphinx's paws.

Recent geological research has been done in the area using new technology, and during one Discovery Channel special, researchers confirmed that it is possible to see that there is a room under the left paw of the Sphinx but the Egyptian directorate of Antiquities does not allow excavation in that area for any reason.

Before that the entity was in the Egyptian land, but of the Atlantean peoples, when there was the exodus from Atlantis to what is now the Spanish or Pyrenees land, and then to Egypt. The name then was Ex-Ter-El. 

[Reading for person #3184-1]:
Before that… the entity was in Atlantis during those periods when there were the separations, just before the breaking up of Poseidia. The name then was Ae-Ne-An. 

[Reading for person #3590-1]:
Before that the entity was in the Yucatan land when the people settled there who came from Atlantis. The entity was a priestess. The name then was Queetel.

During Cayce’s otherworldly journeys, he would often reveal the past lives of those who would come to him for information concerning their health. A number of people who came to Cayce were told by him that they had past lives in the legendary lost land of Atlantis. In fact, Cayce revealed that a vast number of souls who lived past lives in Atlantis have been incarnating to America for a long time now to usher in a new era of enlightened human consciousness. In all, Cayce referred to Atlantis no fewer than seven hundred times over a span of twenty years.
