A teacher should have a creative mind.
God isn't the son of Memory; He's the son of Immediate Experience. You can't worship a spirit in spirit, unless you do it now. Wallowing in the past may be good literature. As wisdom, it's hopeless. Time Regained is Paradise Lost, and Time Lost is Paradise Regained. Let the dead bury their dead. If you want to live at every moment as it presents itself, you've got to die to every other moment.
