In 1985, Merv Griffin was visited by J.Z. Knight, who’s long made a good living by pretending that she could channel Ramtha, a 35,000 year-old spiritual guide given to twisty, Yoda-ish pronouncements. She “summons” the “entity” at around the ten-minute mark, and it’s fairly clear how even someone as cerebral as Linda Evans could have become a true believer.
