I'm reading a very good book titled The Cave of the Ancients and wanted to do some research on the author, T Lobsang Rampa who was supposed to be a student to the Tibetan lamas high in the Himalayas monasteries.
Come to find out this the person claims Tuesday Lobsang Rampa took over the body of Cyril Henry Hoskin.
Read it for yourself
