Wilderness Dwellers
“Mendicants, there are these five kinds of wilderness dwellers. What five? One may be a wilderness dweller because of stupidity and folly. Or because of corrupt wishes, being of wishful temperament. Or because of madness and mental disorder. Or because it is praised by the Buddhas and their disciples. Or for the sake of having few wishes, for the sake of contentment, self-effacement, seclusion, and simplicity. These are the five kinds of wilderness dwellers. But the one who dwells in the wilderness for the sake of having few wishes is the foremost, best, chief, highest, and finest of the five.
