PRISMS
Text: Q.: What is the best substance for induction, conduction, transmission of etheronic energy? A.: "This is as raised power that would be produced from a combination of crystal. This should be rather interesting to this body, for it is very much like that used by the body in destructive forces in the Atlantean sojourn! Not that which caused the cosmic ray, or the death ray, or the healing ray - but the ray that came from setting of the prismatic influences from high heating - it may be from Arcturus or it may be from the Sun; Though Arcturus would be nearer proper. The Sun may be induced to make for destructivee or constructive forces, either one. It's a combination of those forces or rays that may be gathered in certain settings or prisms. It would require a lot of detail in preparing same." Cayce (440-3)
