The Buddha describes the four streams of merit, outflows of good, and supports for ease. The fourth quality is virtue.
Paṭhamapuññābhisanda sutta - Streams of Merit (First)
At Sāvatthi.
"Bhikkhus, there are these four streams of merit, outflows of good, and supports for ease. What four? Here, bhikkhus, a disciple of the noble ones is endowed with experiential confidence in the Buddha — Indeed, the Blessed One is the Worthy One, perfectly enlightened, accomplished in wisdom and conduct, well-gone, knower of the world, unsurpassed leader of persons to be trained, teacher of gods and humans, enlightened, blessed. This is the first stream of merit, outflow of good, and support for ease.
Further again, bhikkhus, a disciple of the noble ones is endowed with experiential confidence in the teachings of the Buddha — Indeed, the Dhamma is well proclaimed by the Blessed One, directly visible, immediate, inviting verification, leading onward, to be personally experienced by the wise. This is the second stream of merit, outflow of good, and support for ease.
Further again, bhikkhus, a disciple of the noble ones is endowed with experiential confidence in the Saṅgha — The community of the Blessed One's disciples is practicing the good way, practicing the upright way, practicing the true way, practicing the proper way; that is, the four pairs of persons, the eight types of individuals—this community of the Blessed One's disciples is worthy of gifts, worthy of hospitality, worthy of offerings, worthy of reverential salutation, the unsurpassed field of merit for the world. This is the third stream of merit, outflow of good, and support for ease.
Further again, bhikkhus, a disciple of the noble ones is endowed with virtues that are dear to the noble ones—unbroken, unblemished, not patchy, untarnished, liberating, praised by the wise, not clung to, leading to collectedness. This is the fourth stream of merit, outflow of good, and support for ease.
These indeed, bhikkhus, are the four streams of merit, outflows of good, and supports for ease."
