87., 88. A wise man should leave the dark state (of ordinary life), and follow the bright state (of the Bhikshu). After going from his home to a homeless state, he should in his retirement look for enjoyment where there seemed to be no enjoyment. Leaving all pleasures behind, and calling nothing his own, the wise man should purge himself from all the troubles of the mind.
