Osho was a Mystic and  Enlightened Master and has made enormous contributions to the world.

One of those is the creation of Active Meditations. He believed that for the modern western man to be able to come to stillness he first needs to move his body, his breath and his emotions. He introduced breath, movement and catharsis into meditation and has designed over 500 active meditations. The most known are Dynamic Meditation and Kundalini Meditation.

He has written numerious books and given thousands of hours of talks which are mostly recorded.

I like Tom Robbin’s Quotes on Osho:

“I recognize the emerald breeze when it rattles my shutters. And Osho is like a hard, sweet wind, circling the planet, blowing the beanies off of rabbis and popes, scattering the lies on the desks of the bureaucrats, stampeding the jackasses in the stables of the powerful, lifting the skirts of the pathologically prudish and tickling the spiritually dead back to life.”

“Jesus had his parables, Buddha his sutras, Mohammed his fantasies of the Arabian night. Osho has something more appropriate for a species crippled by greed, fear, ignorance and superstition: he has cosmic comedy.”

“What Osho is out to do, it seems to me, is pierce our disguises, shatter our illusions, cure our addictions and demonstrate the self-limiting and often tragic folly of taking ourselves too seriously.”

If you are interested, I can always tell you more about Osho
