We experience what is perceived, put together and projected by a whole being in reality. We as identity or self, are a projected part of the whole body also.
The whole body encompasses all that we are and experience, including both our positive and negative extremes.
Becoming a part of our whole is simply being what we are, but involves settling into our existence as a projected actuality. Before this, we are identified with our self and what we experience, exclusive of our relation with our whole as his or her part.
