On November 12, 1933 Edgar Cayce gave a general reading on the Mayan civilization at the request of several A.R.E. members. In making a connection with Atlantis, the reading promptly focused in on the influence of a single prominent Atlantean named Iltar who migrated to the Yucatan just prior to the final destruction of Atlantis:
Then, with the leavings of the civilization in Atlantis (in Poseidia, more specific), Iltar - with a group of followers that had been of the household of Atlan, the followers of the worship of the ONE with some ten individuals - left this land Poseidia, and came westward, entering what would now be a portion of Yucatan. And there began, with the activities of the peoples there, the development into a civilization that rose much in the same matter as that which had been in the Atlantean land. Others had left the land later. Others had left earlier. There had been the upheavals also from the land of Mu, or Lemuria, and these had their part in the changing, or there was the injection of their tenets in the varied portions of the land - which was much greater in extent until the final upheaval of Atlantis, or the islands that were later upheaved, when much of the contour of the land in Central America and Mexico was changed to that similar in outline to that which may be seen in the present. The first temples that were erected by Iltar and his followers were destroyed at the period of change physically in the contours of the land. That now being found, and a portion already discovered that has laid in waste for many centuries, was then a combination of those peoples from Mu, Oz and Atlantis. (5750-1)
Note that Iltar traveled to the Yucatan with a group of followers of the Law of One to build temples and provide a repository for a copy of the records of Atlantis for posterity. The records were said to be in the form of stone tablets.
With the final destruction on Atlantis, the physical contour of what is now Central America was changed as that land also experienced upheavals. The first temples erected by Iltar and his followers were destroyed. The records of Atlantis that were transported to the Yucatan have not yet been recovered, although the readings insist that will eventually happen.
Reading 5750-1 also documents how the Mayan civilization was actually a composite of various sources, including Atlantis, Lemuria, and even the lost tribes of the Hebrew peoples.
Those in Yucatan, those in the adjoining lands as begun by Iltar, gradually lost in their activities; and came to be that people termed, in other portions of America, the Mound Builders. (5750-1)
