I'll play a monk: I'll do Eastern Orthodox Christian 'cause I
  spent a few years experimenting with that tradition and got the
  "gist" of their ethos, even though I'm agnostic now: "Your
  ultimate responsibility is Theosis. Through a synergy between
  your activities and the uncreated energies of God, your every
  breath, thought and action will help bring about the deification
  of the species" There. That sounds good.
