Jiddu Krishnamurti (; 11 May 1895 – 17 February 1986) was a speaker and writer on matters that concerned humankind. In his early life he was groomed to be the new World Teacher but later rejected this mantle and withdrew from the organisation behind it. His subject matter included psychological revolution, the nature of mind, meditation, inquiry, human relationships, and bringing about radical change in society. He constantly stressed the need for a revolution in the psyche of every human being and emphasised that such revolution cannot be brought about by any external entity, be it religious, political, or social.
