My brother, we must make known to many the truth that one person can voluntarily leave his body and allow another person to occupy and revive the abandoned body. Your task is to share this knowledge with people.” Thus, within the walls of the Potala Monastery, the Aged Patriarch taught his disciple Lobsang Rampa. In his wonderful book, Dr. Rampa fulfills the wish of his beloved Mentor. It defines the various branches of man's personality, his 'I', and introduces the uninitiated to the truths and ultimate reality of reincarnation.
