Man's maker was made man that He, Ruler of the stars, might nurse at His mother's breast; that the Bread might hunger, the Fountain thirst, the Light sleep, the Way be tired on its journey; that Truth might be accused of false witnesses, the Teacher be beaten with whips, the Foundation be suspended on wood; that Strength might grow weak; that the Healer might be wounded; that Life might die.

Your wisdom should be without pride.
