釋摩訶衍論 2.10

2.10

本曰：顯示正義者，依一心法有二種門。云何為二？一者心真如門、二者心生滅門。是二種門皆各總攝一切法。此義云何？以是二門不相離故。

The root [text] says: As for 'revealing the correct meaning', relying on the dharma of the one mind, there are two kinds of gates. What are the two? First, the gate of the mind as tathatā; second, the gate of the mind as arising and ceasing. Each of these two gates comprehensively subsumes all dharmas. What does this mean? Because these two gates are not separate from each other.
