Thus have I heard. On one occasion the Blessed One was dwelling at Savatthī in Jeta’s Grove, Anathapiṇḍika’s Park. There the Blessed One said:
“Bhikkhus, those ascetics or brahmins who do not understand aging-and-death, its origin, its cessation, and the way leading to its cessation: these I do not consider to be ascetics among ascetics or brahmins among brahmins, and these venerable ones do not, by realizing it for themselves with direct knowledge, in this very life enter and dwell in the goal of asceticism or the goal of brahminhood.
“But, bhikkhus, those ascetics and brahmins who understand aging-and-death, its origin, its cessation, and the way leading to its cessation: these I consider to be ascetics among ascetics and brahmins among brahmins, and these venerable ones, by realizing it for themselves with direct knowledge, in this very life enter and dwell in the goal of asceticism and the goal of brahminhood.”
