釋摩訶衍論 2.66

2.66

牟尼大覺尊，一代聖說中，
總集有十種，各異說契經。
謂一種為始，十種而為終，
歸本等契經，分明顯說故。

Within the holy teachings of the Muni, the Greatly Awakened Honoured One, throughout his lifetime,
Collected in sum, there are ten kinds of sūtras that speak variously,
Namely, beginning with one kind and ending with ten kinds,
Because sūtras such as the Returning to the Source distinctly explain them.
