Rajneesh, also known as Acharya Rajneesh, Bhagwan Shree Rajneesh, and later as Osho, was an Indian godman, mystic, and founder of the Rajneesh movement.
OSHO is a Buddhist priest (in charge of a temple) honorific title of preceptor or high priest (especially in Zen or Pure Land Buddhism). The same kanji are also pronounced kashō as an honorific title of preceptor or high priest in Tendai or Kegon Buddhism and wajō as an honorific title of preceptor or high priest in Shingon, Hossō, Ritsu, or Shin Buddhism.

With these literally immortal words, Osho both dictates his epitaph and dispenses with his biography. Having previously removed his name from everything, he finally agrees to accept "Osho," explaining that the word is derived from William James' "oceanic." He initially said, “It is not my name, it is a healing sound."
