The Oneness of each to all through God is real, objective, existential. It is an eternal relationship which is shared in by every stick and stone and bird and beast and saint and sinner of the universe. On all, the wooing love of God falls urgently, persuadingly.
The need is for the connection to nature within ourselves; only then can we understand how to act toward nature outside ourselves. Along with the obvious crimes our culture is committing against the natural world, we would be wise to remember that the main crimes are the crimes against our inner nature. From these inner crimes all the outer evil arises. This is the teaching of wisdom.
