“Mendicants, these four who are competent, educated, self-assured, and learned, who have memorized the teachings and practice in line with the teaching, grace the Saṅgha. What four? A monk, a nun, a layman, and a laywoman. These four who are competent, educated, self-assured, and learned, who have memorized the teachings and practice in line with the teaching, grace the Saṅgha.
Whoever is competent and self-assured, learned, a memorizer of the teachings, who lives in line with the teaching—such a one is said to grace the Saṅgha.
A monk accomplished in ethics, and a learned nun, a faithful layman, and a faithful laywoman, too: these grace the Saṅgha, they are the graces of the Saṅgha.”
