Rajneesh, also known as Acharya Rajneesh, Bhagwan Shree Rajneesh, and later as Osho, was an Indian godman, philosopher, mystic, and founder of the Rajneesh movement. He was viewed as a controversial new religious movement leader during his life. He rejected institutional religions, insisting that spiritual experience could not be organized into any one system of religious dogma. As a guru, he advocated meditation and taught a unique form called dynamic meditation. Rejecting traditional ascetic practices, he advocated that his followers live fully in the world but without attachment to it. In expressing a more progressive attitude to sexuality he caused controversy in India during the late 1960s and became known as "the sex guru".
