[35] Then, brahmin, this occurred to me: 'Whatever ascetics or brahmins, overcome by dullness and drowsiness (thīna-middha), resort to remote lodgings in the wilderness and forest thickets — because of the fault of being overcome by dullness and drowsiness, those worthy ascetics and brahmins summon unwholesome (akusala) fear and dread. But I do not resort to remote lodgings in the wilderness and forest thickets overcome by dullness and drowsiness; I am free from dullness and drowsiness. I am one of those noble ones who, free from dullness and drowsiness, resort to remote lodgings in the wilderness and forest thickets.' Seeing in myself this freedom from dullness and drowsiness, brahmin, I attained even greater ease for dwelling in the forest.
