Known as the “Sleeping Prophet”, Edgar Cayce (1877–1945) gave thousands of readings while in a trance-like state.
Topics included health, past lives, reincarnation, and ancient lost civilizations—especially Atlantis.
He described Atlantis in rich detail, far beyond what Plato wrote.
According to Cayce, Poseidia was one of the major cities or regions of Atlantis, specifically the most spiritually and technologically advanced.
A large island region in the western Atlantic Ocean, stretching between what is now Bimini (Bahamas), parts of the Caribbean, and maybe even parts of Florida.
Poseidia was located in the southern portion of Atlantis.
Cayce even claimed that remains of Poseidia would rise again, and predicted:
“Poseidia will be among the first portions of Atlantis to rise again. Expect it in ‘68 and ‘69.” (Reading 958-3)
While the physical rising didn’t happen, some link this to underwater discoveries like the Bimini Road.
Poseidia was a society where spiritual knowledge and advanced science were blended harmoniously.
Citizens were said to work with crystal energy, telepathy, levitation, and even anti-gravity devices.
Central to Poseidia was a massive crystal tower, called the Tuaoi Stone.
It was used to draw power from the sun, stars, and the Earth's magnetic fields.
Powered everything from transportation to healing and communication.
When misused, this crystal may have caused catastrophic destruction, contributing to the fall of Atlantis.
Flying vehicles, underground tunnels, and even interplanetary contact were hinted at in Cayce’s descriptions.
He spoke of genetic manipulation, including the creation of hybrids, sometimes called the “things” or the beast-men—early artificial beings.
Atlantis, including Poseidia, had two major factions:
Sons of the Law of One: Spiritually enlightened, believed in unity, reincarnation, and service to others.
Sons of Belial: Materialistic, self-serving, and exploitative. Focused on power and domination.
Poseidia was home to the Law of One, and its culture embodied harmony, balance, and consciousness.
The tension between these groups led to warfare, misuse of tech, and eventually, destruction
According to Cayce, Poseidia survived the first Atlantean destruction, around 50,000 B.C., and even the second, around 28,000 B.C.
It was only during the final destruction, around 10,000–12,000 B.C., that Poseidia was submerged entirely.
Cayce suggested that Atlantean souls reincarnated throughout time—especially in modern America, often with karmic ties to their past lives in Poseidia.
Poseidia in Cayce’s work isn’t just a mythic city—it’s a symbol of a spiritually advanced human state that was lost due to ego, imbalance, and misuse of power.
It echoes the Fall of Man, the loss of Eden, or the Tower of Babel—a once-golden civilization corrupted by pride.
Its memory is thought to live within the collective unconscious, and Cayce believed that rediscovering Poseidia (physically or spiritually) would be part of humanity’s awakening and return to higher consciousness.
Bimini Road (Bahamas): Believed by some to be part of Poseidia's ruins—discovered in 1968, the same year Cayce "predicted" something would rise.
Crystal healing, Atlantean energy work, and Law of One philosophies often draw from Cayce’s Poseidia narrative.
