The OSHO teachings defy categorization, covering everything from the individual quest for meaning to the most urgent social and political issues facing society today. His books are not written but are transcribed from audio and video recordings of extemporaneous talks given to international audiences over a period of 35 years. Osho has been described by the Sunday Times in London as one of the "1000 Makers of the 20th century" and by American author Tom Robbins as "as the most dangerous man since Jesus Christ".
OSHO is also known for his revolutionary contribution to the science of inner transformation, with an approach to meditation that acknowledges the accelerated pace of contemporary life. His unique "Active Meditations" are designed to first release the accumulated stresses of body and mind, so that it is easier to experience the thought-free and relaxed state of meditation.
