There is an irreducible Principle of Being behind all other beings, an Unconditioned Power behind all lesser and limited powers, a final Reality which was never born or put together. Call it what you will, you can neither define nor describe it adequately: men do not perceive it because they do not have the necessary faculty for perceiving it, for that is a faculty which has nothing to do with the affairs of their little ego and its little world. But they can awaken this insight, nurture it, develop it.
