Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 26.2.4_6

26.2.4_6

aṃho vā etad yajñasya yady atikrāntam ulbaṇam sadasyo bodhayeta iti tasmān na atikrāntam ulbaṇam sadasyo bodhayeta iti ha sma āha paiṅgyaḥ / (soma: chandomāh)

"This is indeed a distress of the sacrifice, if the sadasya should remind him of an error that has passed beyond. Therefore the sadasya should not remind him of an error that has passed beyond," so said Paiṅgya.
