"Rajneesh" Chandra Mohan Jain (December 11, 1931 – January 19, 1990), also known as Acharya Rajneesh from the 1960s onwards, the name Osho in 1989, was an Indian mystic, guru and philosopher. A professor of philosophy, he travelled throughout India in the 1960s as a public speaker. Oshodhara indicates the living stream of Osho. It indicates presence of living masters in the tradition.

Osho, the greatest mystic and visionary of our times, left His body in January 1990. The movement that He initiated and piloted during His lifetime lost its track immediately thereafter. This situation by and large continues even today.

With emergence of Osho Sadguru Trivir, a group of Osho's three enlightened disciples (the trinity of Osho Siddhartha, Osho Shailendra and Ma Osho Priya). It became possible to keep the tradition alive. Based on Osho's spiritual vision and their own experiences, twelve levels of Samadhi Programs, each of 7 days duration, came into existence, through which they started guiding the seekers towards Samadhi and Enlightenment.
