A Wilderness Dweller
Araññaka Sutta (AN 4:263)
“Endowed with (any of) four qualities, a monk isn’t fit to stay in isolated forest & wilderness lodgings. Which four? (He is endowed) with thoughts of sensuality, with thoughts of ill will, with thoughts of harmfulness, and he is a person of weak discernment, dull, a drooling idiot. Endowed with (any of) these four qualities, a monk isn’t fit to stay in isolated forest & wilderness dwellings.

Endowed with these four qualities, a monk is fit to stay in isolated forest & wilderness dwellings.”
