The osho dynamic meditation was developed by a man named Rajneesh Chandra Mohan Jain. He was born in India in 1931 and became enlightened when he was 21.Towards the late sixties he developed the Dynamic Meditation method as an alternative to the traditional seated method of meditation. He explained that this was more conducive to the common man who had to keep up with the busy world around him.
It was in the seventies that people started calling Rajneeshby the title of Bhagwan Shree Rajneesh. By this time he had found followers all over the world. These followers slowly made their way to India where they became his disciples. For several years he taught them his way and means and the discourses he held every morning have now been compiled into books. These books and other tantra books are widely available online for purchase. Some of the discourses which were recorded are available as osho mp3 files as well.
He visited the U.S. for relief from a physical ailment and ended up staying there for a few years. During this time he established a commune called Rajneeshpuram in the Oregon desert. However, due to the unscrupulous activities of some within the commune, Bhagwan Shree Rajneesh was placed under arrest and thereafter deported. After visiting several countries to spread his message, he returned to his native country where took on a simpler name, that of Osho, and renamed his ashram Osho Commune International. He departed this world in January 1990.
