The Long Āgama Sūtra 1.6

1.6

時，諸比丘於乞食後集花林堂，各共議言：「諸賢比丘！唯無上尊為最奇特，神通遠達，威力弘大，乃知過去無數諸佛，入於涅槃，斷諸結使，消滅戱論。又知彼佛劫數多少，名號、姓字，所生種族，其所飲食，壽命脩短，所更苦樂。又知彼佛有如是戒，有如是法，有如是慧，有如是解，有如是住。云何，諸賢！如來為善別法性，知如是事，為諸天來語，乃知此事？」

It was then that the monks gathered in the Flowering Grove Hall after soliciting alms. They engaged in a discussion with each other: “Venerable monks, only the unsurpassed sage is so extraordinary! His miraculous powers are far-reaching, and his authority is tremendous. He has come to know the countless buddhas of the past who have entered nirvāṇa, broken the bonds, and eliminated idle speculation.”

“He also knows how many eons ago those buddhas lived as well as their names, surnames, the clans to which they were born, the meals they had, the length of their lives, and what suffering and happiness they experienced.”

“He also knows that those buddhas possessed such precepts, such principles, such wisdom, such liberation, and such abodes.”

“What do you think, gentlemen? Does the Tathāgata know this by discerning well the nature of things, or does he know these things because the gods come and tell him about them?”
