大般若波羅蜜多經般若理趣分述讚 3.71

3.71

讚曰：此第二段如來智印金剛法門，顯由二行得自體果。文有三等，竝同前釋。此即第一標所說法門之號，以妙智印任持一切佛甚深法。佛甚深法體性難知，名為祕密。以一智印持諸佛法，一切佛法竝入此故，名為任持。今說此法令勤趣入，故名為門。以能破壞一切生死智體堅實，故名金剛。

The Commentary says: This second passage on the adamantine dharma gate of the Tathāgata's wisdom-seal reveals the attainment of the fruit of one's own essence by means of two practices. The text has three sections, all like the previous explanation. This is the first, marking the title of the dharma gate spoken: by means of the wondrous wisdom-seal, it upholds all the profound Dharmas of the Buddhas. Because the intrinsic nature of the profound Dharmas of the Buddhas is difficult to know, it is called 'secret'. Because it upholds all Buddhadharmas with a single wisdom-seal, and all Buddhadharmas enter into this, it is called 'maintaining'. Now, this Dharma is expounded so that they may diligently enter into it; hence it is called a 'gate'. Because the nature of this wisdom is solid and capable of destroying all cyclic existence, it is called 'adamantine'.
