三輪義，以七門分別，一出體、二辨名、三廢立、四顯相、五三乘能起、六三身所作、七有情化別。

The meaning of the three wheels is distinguished by seven categories: 1. identifying the essential nature; 2. explaining the name; 3. inclusion and exclusion; 4. revealing the characteristics; 5. the capacity of the three vehicles to initiate them; 6. the operations of the three bodies; 7. distinctions in transforming sentient beings.
