The Long Āgama Sūtra 23.13

23.13

報言：「我聞有沙門瞿曇釋種子出家成道，於俱薩羅國人間遊行，詣佉㝹婆提村北尸舍婆林，有大名稱，流聞天下，如來、至真、等正覺，十號具足，於諸天、世人、沙門、婆羅門中，自身作證，為人說法，上中下言，皆悉真正，義味具足，梵行清淨。如此真人，宜往覲現。諸婆羅門！我又聞瞿曇知三種祭祀、十六祀具，今我眾中先學舊識所不能知，我今欲大祭祀，牛羊已備，欲詣瞿曇問三種祭祀、十六祀具，我等得此祭祀法已，功德具足，名稱遠聞。」

Kūṭatāṇḍya replied, “I’ve heard this: ‘The ascetic Gautama of the Śākyans who had left the home life and achieved awakening has been touring among the people of Kośala. He arrived north of [Khānumata], and stopped to stay in the rosewood grove there. His great fame is heard throughout the world: “He’s a Tathāgata, Arhat, and Completely Awakened One who has perfected the ten epithets!” Among gods and worldly people, be they Māras, Brahmās, ascetics, or priests, he teaches for others what he himself has realized. His words are all genuine in the beginning, middle, and end, complete in content and expression, and purify the religious life. It’s fitting to have an audience with such a realized person.’

“Priests, I’ve also heard that Gautama knows the three kinds of ritual sacrifice and sixteen ritual requisites. Now, previous generations and elders in our assembly haven’t known these things, but I want to make a great sacrifice and have prepared the cattle and sheep for it. I’m going to visit Gautama to ask him about the three kinds of ritual sacrifice and sixteen ritual requisites. Once we’ve acquired these ways of ritual sacrifice, we’ll perfect their virtues, and our fame will be heard far and wide.”
