Bhagwan Shree Rajneesh, Later Osho.

I enjoyed reading his early works but he was wrong and he did more harm than good. He teaches moral relativity. At least that's what it ended up as.

This material world has no safe haven. None. The spiritual world is the safe haven but it's conditional. While there are natural laws that if we break them we pay the price there are spiritual laws, too that we need to understand in order to get the most out of this material life.

Your body is a temple. Right between the ears is the temple. It's a sanctuary but it's not the place where you will find eternal sanctuary. This body is temporary but you and your personality are immortal. Cultivate this and it doesn't matter what others do. We all serve the Supreme Godhead regardless of whether we do so consciously or not. In conscious service we will find joy. Helping others to achieve this sovereign service is not slavery. Slavery is belief in the material world and the idea that manipulating it will lead to peace.

Karma is proof of work and the Karma we have is very old, deep and not fully understood.
