The art of peace is medicine for a sick world. There is evil and disorder in the world because people have forgotten that all things emanate from one Source. Return to that Source and leave behind all self-centered thoughts, petty desires, and anger. Those who are possessed by nothing possess everything.
Indivisible oneness is the creative energy that turns a seed into a maple tree, or a watermelon or a human being or anything else that's alive. It's invisible, omnipresent, and absolutely indivisible. We can't divide oneness. Meditation offers us the closest experience we can have of rejoining our Source and being in the oneness at the same time that we're embodied. This means we have to tame our ego.
