2.63

"Why is this?" From here down is the second [part], generally explaining the two knowledges of the Buddhas. This is designated as citing the past practices of the Buddhas to explain the reasons for the two knowledges. Why is the real knowledge of the Buddhas profoundly deep and immeasurable? And why is it said that the gate to their wisdom is difficult to understand and difficult to enter? Because the Buddha formerly drew close to hundreds of thousands of myriads of koṭis [of Buddhas] and completely carried out the practices of the Buddhas of former days, he attained these two knowledges to be profound and subtle. Within this explanation itself there are three: first, from "The Buddha formerly drew close to" onwards clarifies the root of the practices; second, from "completely carried out [the practices of] the Buddhas" onwards directly clarifies the carrying out of the practices; third, the single phrase "their names are universally heard" concludes and manifests [it].
