So, if we must give a general formula applicable to all kinds of soul, we must describe it as the first actuality [entelechy] of anatural organized body.
The soul is something which contains the body. The body doesn't contain the soul. The soul, if we put it into modern language, is the entire complex of relationships in whose context this organism exists.
I sing the body electric,
The armies of those I love engirth me and I engirth them,
They will not let me off till I go with them, respond to them,
And discorrupt them, and charge them full with the charge of the soul.
There are souls which, crab-like, crawl continually toward darkness, going back in life rather than advancing in it, using what experience they have to increase their deformity, growing worse without ceasing, and becoming steeped more and more thoroughly in an intensifying wickedness.
The Kingdom of Heaven is within us. God is within us. He is the Soul of our souls. See Him in your own soul. That is practical religion. That is freedom.
