The first two stages of life, that of student and householder, are for doing. The second two stages of life, that of hermit and renunciant, are for undoing. Adapted for the Western mind, per T.S. Eliot, we advance for a while and then we retreat, arriving where we started from and knowing the place for the first time.
What is the difference between good judgement and bad judgement? Same as the difference between good unicorns and bad unicorns. The renunciant has dispensed with the fiction of judgement. He has no enemies.
