Samyuktagama (Sanskrit fragments) 276.15

276.15

諸比丘尼白尊者難陀言：「我等今日聞尊者教，令我等問，告我等言：『汝等若未解者，今悉當問；已解者當言解，未解者當言不解。於我所說義，已解者當奉持，未解者當復更問。』我等聞此，心大歡喜，未解義者，今日當問。」

The nuns said to Venerable Nanda, “Today, we will listen to the venerable’s teaching. To have us ask questions, tell us, ‘If any of you don’t understand yet, you may ask questions now. If you’ve understood, then say, “Understood.” Those of you who don’t yet understand say, “I don’t understand.” Those who’ve understood what I said should accept and keep it. Those who haven’t yet understood should question me again.’ We’ll be very happy to hear this, and those of us who don’t yet understand your meaning will ask questions today.”
