sn.36.27 Saṁyutta Nikāya (Linked Discourses)
Ascetics and Brahmins (1st)
“Mendicants, there are these three feelings.What three?
Pleasant, painful, and neutral feeling.
There are ascetics and brahmins who don’t truly understand these three feelings’ gratification, drawback, and escape.
I don’t regard 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.
