In his biography of Geller, "Uri: A Journal of the Mystery of Uri Geller" (1974) Puharich claimed that with Geller he had communicated with super intelligent computers from outer space. According to Puharich the computers sent messages to warn humanity that a disaster is likely to occur if humans do not change their ways. Puharich claimed that extraterrestrial beings had communicated to him that Geller was the chosen savior of humanity and had been given the ability to contact flying saucers and perform paranormal phenomena such as psychokinesis, spoon bending, telepathy and teleportation. He also claimed to have experienced poltergeist phenomena with Geller. The psychologist Christopher Evans who reviewed the book in the "New Scientist", wrote that although Puharich believed in every word he had written, the book was credulous and "those fans of Geller's who might have hoped to have used the book as ammunition to impress the sceptics. They will be the most disappointed of all". James Randi has written the biography contained "silly theories" but was "both a boost and a millstone to Geller".
