In 1971, Puharich met Israeli psychic Uri Geller and endorsed him as a genuine psychic (see below). Puharich wrote a supportive 1974 biography of Geller, a subject he had investigated with the help of Itzhak Bentov, among others. He also investigated and thought favorably of the Brazilian psychic surgeon Zé Arigó, providing an afterword for his 1974 biographer. Puharich also investigated Mexican psychic surgeon Pachita. One of his books is "The Sacred Mushroom: Key to the Door of Eternity", describes his work with psychics.
