三聚戒七門分別（釋名一　論體二　辨相三　制立四　大小不同五　大小異六　總別七）

The three clusters of precepts are distinguished in seven gates: (1. Explaining the names; 2. Discussing the essence; 3. Distinguishing the characteristics; 4. Establishment; 5. Differences between Mahāyāna and Hīnayāna; 6. Further distinction between Mahāyāna and Hīnayāna; 7. General and specific).
