Science is concerned about quantity; religion is concerned about quality. Religion is concerned with the art of how to live life and how to die life.
Religion in the West has a very wrong connotation. It has almost reached to a point where the very word 'religion' creates a repulsion, where the very word 'religion' reminds one of dead churches and dead priests. It reminds one of serious looking people, long faces. It has lost the capacity to dance, to sing, to celebrate. And when a religion has lost the capacity to dance, to celebrate, to sing, to love, just to be, then it is no more religion - it is a corpse, it is theology. Theology is dead religion.
Never belong to a crowd; Never belong to a nation; Never belong to a religion; Never belong to a race. Belong to the whole existence. Why limit yourself to small things? When the whole is available.
Jesus was a crackpot.
So many religions are there because so many people are unhappy. A happy person needs no religion; a happy person needs no temple, no church - because for a happy person the whole universe is a temple, the whole existence is a church. The happy person has nothing like religious activity because his whole life is religious.
In the East, all the religions preach egolessness. So in the East, everybody is against the ego from the very beginning.
