At Sāvatthī.

“There are ascetics and brahmins who don’t completely understand old age and death, their origin, their cessation, and the practice that leads to their cessation. They don’t completely understand rebirth … continued existence … grasping … craving … feeling … contact … the six sense fields … name and form … consciousness … They don’t completely understand choices, their origin, their cessation, and the practice that leads to their cessation. I don’t deem them as true ascetics and brahmins. Those venerables don’t realize the goal of life as an ascetic or brahmin, and don’t live having realized it with their own insight.
