The 'message' that osho preached is nothing new, is was not some great breakthrough in conciousness, it was merely the messages from others packaged differently.
IMO this man lived for the controversy he caused by his actions, legal and illegal, his actions are what gained him attention, not his rehashed message, taken from Buddhism and Hinduism, and a few other belief systems.

If you are following another, the path is not your own.
