大方廣佛華嚴經隨疏演義鈔 35.40

35.40

疏「末後偈初句」下，三約佛性。即隨難重顯種性具足三佛性義，即《佛性論》第二卷第三顯體分〈三因品〉。論云「復次佛性體有三種三性所攝義，應知。三種者，所謂三因。三種佛性三因者，一應得因、二加行因、三圓滿因。初即二空所顯真如，由此應得菩提心，乃至道後法身故。二加行因者，謂菩提心，由此心故得三十七品、十度十地，乃至道後法身。三圓滿因者，即加行因，由此故得一切圓滿。三種佛性者，應得因中具有三性，一住自性性、二引出性、三至得果性。」釋曰：住自性者，謂道前凡夫位。引出性者，從發心已上窮有學聖位。至得果性者，無學聖位。

Regarding the Commentary's statement, "From the first line of the final verse..." onwards: The third is in terms of buddha-nature. That is, following the difficult points, it re-clarifies the meaning that the gotra is endowed with the three buddha-natures. This comes from the *Buddha-Nature Treatise* (*Buddhagotraśāstra*), fascicle two, part three, "Revealing the Essence," chapter "The Three Causes." The treatise states: "Furthermore, it should be known that the essence of buddha-nature has three kinds, subsumed under the three natures. The three kinds are what are called the three causes. The three causes of the three kinds of buddha-nature are: first, the cause of what should be attained; second, the cause of applied practices; third, the cause of fulfillment. The first is the tathatā revealed by the two kinds of emptiness; by this, one should attain bodhicitta, up to the post-path dharmakāya. Second, the cause of applied practices: this refers to the bodhicitta; by this mind, one attains the thirty-seven aids to awakening, the ten pāramitās, and the ten stages, up to the post-path dharmakāya. Third, the cause of fulfillment: this is the cause of applied practices; through this, all is fulfilled. As for the three kinds of buddha-nature: within the cause of what should be attained, the three natures are fully present: first, the nature abiding in its own nature; second, the nature drawn forth; third, the nature of attaining the fruit." Explanation: "Abiding in its own nature" refers to the stage of ordinary beings before the path. "The nature drawn forth" refers to all the stages of the noble ones who are still in training, from the generation of the mind on up. "The nature of attaining the fruit" refers to the stage of the noble ones beyond training.
