Wilderness
“Mendicants, when a mendicant has four qualities they’re not ready to frequent remote lodgings in the wilderness and the forest. What four? They have sensual, malicious, and cruel thoughts; or they’re witless, dull, and idiotic. When a mendicant possesses these four qualities they’re not ready to frequent remote lodgings in the wilderness and the forest.
