Edgar Cayce
The Tuaoi Stone (also called the Firestone, Great Crystal, or Terrible Crystal) is one of the most famous and detailed elements from Edgar Cayce’s psychic readings on Atlantis.
Cayce described it as the central power source and technological heart of Atlantean civilization. It was a massive crystal used to harness, concentrate, and direct cosmic and solar energy for practical and spiritual purposes.
Physical Description and Appearance
According to Cayce’s readings, the Tuaoi Stone was:
- A large cylindrical crystal (described as “glass” in modern terms).
- Cut with facets in a precise manner.
- Topped with a capstone that helped centralize and focus the power.
- In later periods, described as being in the form of a six-sided figure.
Here is one of the most direct descriptions from the readings:
“As to describing the manner of construction of the stone, we find it was a large cylindrical glass (as would be termed today), cut with facets in such a manner that the capstone on top of same made for the centralizing of the power or force, that concentrated between the end of the cylinder and the capstone itself.”
— Edgar Cayce Reading 440-5
Another reading (2072-10) adds:
“It was in the form of a six-sided figure, in which the light appeared as the means of communication between infinity and the finite… Later this came to mean that from which the energies radiated, as of the center from which there were the radial activities guiding the various forms of transition or travel through those periods of activity of the Atlanteans.”
It was a highly polished, faceted crystalline structure — not a natural uncut stone, but a precisely engineered crystal device.
How the Tuaoi Stone Worked
The stone functioned as an energy transducer and amplifier. It could:
- Gather and concentrate energy from the sun and other stars (cosmic radiation).
- Combine this energy with other elements and store it.
- Release the energy in controlled or directed forms.
Its main applications included:
- Power generation for the entire civilization.
- Propulsion of vehicles — airships, surface ships, and submarines — using invisible rays (through a form of induction or remote control).
- Healing and regeneration of the human body (“the bodies of individuals were regenerated by the burning — through the application of the rays from the stone”).
- Communication with higher spiritual forces and between distant locations.
- Amplification of mental and spiritual energies.
Cayce emphasized that when used correctly (under the guidance of trained initiates), it was a constructive and even spiritual tool. However, when misused for selfish or destructive purposes, it became extremely dangerous.
Location in Atlantis
The Tuaoi Stone was housed in a special temple or power station, often referred to in connection with the main temple complex of Atlantis. It was not a portable object but a massive, fixed installation — essentially the central power plant of the civilization.
Role in the Destruction of Atlantis
Cayce stated that the misuse of the Tuaoi Stone (and similar crystals) was one of the major factors that led to the final destruction of Atlantis. The Atlanteans eventually tuned the stone to too high a frequency or used its power destructively, which contributed to massive geological upheavals (earthquakes and volcanic activity) that sank the land.
Firestone of the Utler
This great Atlantean crystal was the Firestone of the Utler. It existed as a star keeper cylindrical quartz crystal, cut as an eight-sided prism. And this was a transmitter of the intergalactic forces that poured into your Earth’s atmosphere — solar, lunar, and stellar energies poured into Atlantis — and which generated a superpower beyond description, an electromagnetic force for all of the systems of energy that sustained the lives that you lived as Atlanteans.
