五品十善義四門分別（一釋名　二開合辨相　三約就人位辨其通局　四所治同異）

The meaning of the five grades of the ten wholesome actions is distinguished in four gates: 1. Explaining the name; 2. Distinguishing characteristics by opening and combining; 3. Distinguishing universality and particularity with reference to persons and stages; 4. Sameness and difference in what is remedied.
