Rilbur Rinpoche, a venerable high lama and historian who was imprisoned for many years by the Chinese, tells of several adepts who managed to eject their consciousness at will (the practice of powa) while imprisoned with him. 'I saw many people who sat down in the corner of their cell and deliberately passed away to another realm. They weren't ill and there was nothing wrong with them. The guards could never believe it!' he said.
