Once you arrive {at a spontaneous awareness of the Great Oneness}, remember: it isn't necessary to struggle to maintain unity with it. All you have to do is participate in it.
One might talk about the sanity of the atom the sanity of space the sanity of the electron the sanity of water- For it is all alive and has something comparable to that which we call sanity in ourselves. The only oneness is the oneness of sanity.
I believe in the absolute oneness of God and, therefore, also of humanity. What though we have many bodies? We have but one soul. The rays of the sun are many through refraction. But they have the same source. I cannot, therefore, detach myself from the wickedest soul (nor may I be denied identity with the most virtuous).
Does one scent appeal more than another? Do you prefer this flavor, or that feeling? Is your practice sacred and your work profane? Then your mind is separated: from itself, from oneness, from the Tao.
