sn48.40:5.1 While a mendicant is meditating—diligent, keen, and resolute—the faculty of equanimity arises.
sn48.40:5.2 They understand:
sn48.40:5.3 ‘The faculty of equanimity has arisen in me. And that has a basis, a source, a condition, and a reason.
sn48.40:5.4 It’s not possible that the faculty of equanimity will arise without a basis, a source, a condition, or a reason.’
sn48.40:5.5 They understand the faculty of equanimity, its origin, its cessation, and where that faculty of equanimity that’s arisen ceases without remainder.
sn48.40:5.6 And where does that faculty of equanimity that’s arisen cease without remainder?
sn48.40:5.7 It’s when a mendicant, going totally beyond the dimension of neither perception nor non-perception, enters and remains in the cessation of perception and feeling.
sn48.40:5.8 That’s where the faculty of equanimity that’s arisen ceases without remainder.
sn48.40:5.9 They’re called a mendicant who understands the cessation of the faculty of equanimity, and who applies their mind to that end.”
