This is essentially the argument for the soul: it holds reality together, it is my offscreen director, my presiding intelligence. I can think, talk, work, love, and dream, all because of the soul, yet the soul doesn't do any of these things. It is me... Everything that makes the difference between life and death must cross into this world via the soul... Soul is a connection between the world of the five senses and a world of inconceivable things like eternity, infinity, omniscience, grace, and every other quality unmanifest.
When Mother Teresa was asked what would happen to her congregation after she had gone, she is said to have responded:
"A person emptier than myself will come along."
The implication here is that the greatness of a person lies in the depth of his or her own self-emptying. Another implication is that what is emptied of oneself will be filled with the self of God. Poverty as a chosen life-style is precisely this:
"To empty oneself of all that one is and has so that all will be at the disposal of the Lord."
