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.
By meditating on the breath and the power within and behind the breath, we realize in the deepest levels of our being that our life is sustained by God. We do not breathe by our own will; God is sustaining our life and everything else in creation... We are born into this world and we will die and live this world. Our first breath and our last breath, the two most important events in our life, are not in our conscious control. Because our breathing is automatic and involuntary, it is easy to forget about the gift of breath — gift of God.
