We think that there is singleness within us, and communality outside us. Outside of us is the communal in relation to the external, while singleness refers to us. We are single if we are in our Selves, but communal in relation to what is outside us. But if we are outside of our Selves, then we are single and selfish in the communal. Our Self suffers privation if we are outside ourselves, and thus it satisfies its needs with communality.
