There are three feelings, and a meditator practicing immersion can understand them.
“Mendicants, there are these three feelings. What three?
Pleasant, painful, and neutral feeling. These are the three feelings.
Stilled, aware,
a mindful disciple of the Buddha
understands feelings,
the cause of feelings,
where they cease,
and the path that leads to their ending.
With the ending of feelings, a mendicant
is hungerless, quenched.”
