三佛義七門分別（釋名義一　辨相二　約時分別三　明因四　常無常分別五　說不說分別六　次第分別七）

The doctrine of the three Buddha [bodies] is distinguished in seven sections: (1. Explaining the names and meanings; 2. Distinguishing their characteristics; 3. Distinguishing according to time; 4. Clarifying their causes; 5. Distinguishing permanence and impermanence; 6. Distinguishing preaching and non-preaching; 7. Distinguishing their sequence).
