276.p14

Venerable Nanda said to the nuns, “Sisters, you should question me as I teach the Dharma for you now. Those of you who understand should say, ‘Understood.’ If you don’t understand, then you should say, ‘I don’t understand.’ If you do understand the meaning of what I say, then you should accept and keep it well. If you don’t understand it, you should question me again, and I will explain it for you.”
