So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. There the Buddha addressed the mendicants: “Mendicants!” “Venerable sir,” they replied. The Buddha said this:

“Mendicants, a mendicant with six factors is worthy of offerings dedicated to the gods, worthy of hospitality, worthy of a teacher’s offering, worthy of veneration with joined palms, and is a supreme field of merit for the world. What six? It’s a mendicant who, when they see a sight with their eyes, is neither happy nor sad. They remain equanimous, mindful and aware. When they hear a sound with their ears … When they smell an odor with their nose … When they taste a flavor with their tongue … When they feel a touch with their body … When they know a thought with their mind, they’re neither happy nor sad. They remain equanimous, mindful and aware. A mendicant with these six factors is worthy of offerings dedicated to the gods, worthy of hospitality, worthy of a teacher’s offering, worthy of veneration with joined palms, and is a supreme field of merit for the world.”

That is what the Buddha said. Satisfied, the mendicants were happy with what the Buddha said.
