I think the soul is what the poets have tried to capture through the ages with their words. In a parables class this fall, I used the phrase "invades the semicolon between one heartbeat and the next" to describe the Good News. I think the soul lives in that pause - that semicolon.
In honor and celebration of my friends and colleagues in Parables, I quote the words of ee cummings:
almighty God! I thank thee for my soul; & may I never die spiritually into a mere mind through disease of loneliness
