Osho explains why he is deliberately inconsistent and contradictory.
My effort in answering you is not to demystify existence but to mystify it more. Hence my contradictions. I cannot be consistent, I am not answering you. I cannot be consistent, because I am not here to make you more knowledgeable. If I am consistent, you will have a body of knowledge – very satisfying to the mind, nourishing, strengthening, gratifying.
I am deliberately inconsistent, contradictory, so that you cannot make any body of knowledge out of me. So if one day you start gathering something, another day I take it away. I don’t allow you to gather anything. Sooner or later, you are bound to be awakened to the fact that something totally different is transpiring here. It is not that I am giving you some dogma to be believed in, some philosophy to be lived by, no, not at all. I am utterly destructive, I am taking everything away from you.
