All that is real in me is God; all that is real in God is I. The gulf between God and me is thus bridged. Thus by knowing God, we find that the kingdom of heaven is within us.
This idea of body is a simple superstition. It is superstition that makes us happy or unhappy. It is superstition caused by ignorance that makes us feel heat and cold, pain and pleasure.
We must always remember that God is Love. "A fool indeed is he who, living on the banks of the Ganga, seeks to dig a little well for water. A fool indeed is the man who, living near a mine of diamonds, spends his life in searching for beads of glass." God is that mine of diamonds. We are fools indeed to give up God for legends of ghosts or flying hobgoblins. It is a disease, a morbid desire.
The attempt is to kill the false "I", so that the real "I", the Lord, will reign. "I the Lord thy God am a jealous God. Thou shalt have no other gods before me," say the Hebrew scriptures.
God is cruel and not cruel. He is all being and not being at the same time. Hence He is all contradictions. Nature also is nothing but a mass of contradictions.
Realize your true nature. That is all there is to do. Know yourself as you are - infinite Spirit. That is practical religion. Everything else is impractical, for everything else will perish.
