‘The Saṅgha of the Buddha’s disciples is practicing the way that’s good, direct, systematic, and proper. It consists of the four pairs, the eight individual persons. This is the Saṅgha of the Buddha’s disciples that is worthy of offerings dedicated to the gods, worthy of hospitality, worthy of a religious donation, worthy of greeting with joined palms, and is the supreme field of merit for the world.’
