‘When I eat my dinner, my thinking mind does not digest it; something else digests it. Some other power pumps my blood and circulates it through my body. My hair and nails do not tell me they grow; they grow while I pay no attention. Something else is living in this body. The part I call myself is only a little part of the whole. I cannot refuse to see without closing my eyes. Whether I want to hear or no, sound vibrates on the drum of my ear. The activities of my eyes and ears do not belong to me; they belong to something within me. So we discover that what we call ourselves, our ego, is a very small part of us.’ (Zen Pivots)
Some of the rest is what I call life force.
