Osho has spoken on virtually every topic of concern to modern man and rise of his consciousness. He has answered questions submitted to him, or comments on the teachings of other mystics and religious traditions. All these talks have been recorded and almost all of them are available as books, many are available as audiotapes, or videotapes.

This is what osho has to say about his “sayings”

“So always remember, whatsoever I say to you, you can take it in two ways. You can simply take it on my authority "Osho says so, it must be true" -- then you will suffer, then you will not grow. Whatsoever I say, listen to it, try to understand it, implement it in your life, see how it works, and then come to your own conclusions. They may be the same, they may not be. They can never be exactly the same because you have a different personality, a unique being. Whatsoever I am saying is my own. It is bound to be in deep ways rooted in me. You may come to similar conclusions, but they cannot be exactly the same. So my conclusions should not be made your conclusions. You should try to understand me, you should try to learn, but you should not collect knowledge from me, you should not collect conclusions from me. Then your mindbody will grow.”
