Jon loaned me this book and it's pretty good

“He visited my class, we set some poetry readings up for him, and we set up his Free University meeting room and place. I think the title of the class we said he would teach was Tantric Yoga—no it was Telepathic Communication. His class was a tremendous success, though not because of his lecturing on telepathy. The first night he was supposed to teach it, we walked with him to the student union building. The room was on the first floor and was packed with people sitting quietly, intently, as though waiting for Jim Jones to pass the Kool-Aid. Either it was that or something else, something false, levy picked up on, and he simply walked on by the door and out the side. I thought for a moment of going in and telling them it was another no-show, but what the hell. We all walked over to the 602 Club and then thought no more about it, until Ann Krooth told me that levy’s class was one of the most successful in all the Free University. People there assumed he was trying to reach them telepathically, and many of them heard him, as they sat there, meditating in the classroom. That class went on for several months after levy had returned to Cleveland—months after levy was no longer alive.”
