sn48.40:4.1 While a mendicant is meditating—diligent, keen, and resolute—the faculty of happiness arises.
sn48.40:4.2 They understand:
sn48.40:4.3 ‘The faculty of happiness has arisen in me. And that has a basis, a source, a condition, and a reason.
sn48.40:4.4 It’s not possible that the faculty of happiness will arise without a basis, a source, a condition, or a reason.’
sn48.40:4.5 They understand the faculty of happiness, its origin, its cessation, and where that faculty of happiness that’s arisen ceases without remainder.
sn48.40:4.6 And where does that faculty of happiness that’s arisen cease without remainder?
sn48.40:4.7 It’s when, giving up pleasure and pain, and disappearance former happiness and sadness, a mendicant enters and remains in the fourth absorption, without pleasure or pain, with pure equanimity and mindfulness.
sn48.40:4.8 That’s where the faculty of happiness that’s arisen ceases without remainder.
sn48.40:4.9 They’re called a mendicant who understands the cessation of the faculty of happiness, and who applies their mind to that end.
