You will never get to the irreducible definition of anything because you will never be able to explain why you want to explain, and so on. The system will gobble itself up.
We want to worship a living God. I have not seen anything but God all my life, nor have you... He is everywhere, saying, "I am." The moment you feel "I am," you are conscious of Existence. Where shall we go to find God if we cannot see Him in our own hearts and in every living being?
For if you know what you want, and will be content with it, you can be trusted. But if you do not know, your desires are limitless and no one can tell how to deal with you. Nothing satisfies an individual incapable of enjoyment.
There are times when you don't know yourself. There are times when you don't want to know yourself. There are times when you want to be what you have never allowed yourself to be before.
