四無礙義七門分別（釋名一　辨相二　隨義具論三　相對辨四　大小有無五　大小不同六　對力無畏彰別本末七）

The doctrine of the four unimpeded knowledges is distinguished in seven sections: 1. Explaining the names; 2. Distinguishing the characteristics; 3. Full exposition according to their meanings; 4. Comparative analysis; 5. Presence and absence in the Mahāyāna and Hīnayāna; 6. Differences between the Mahāyāna and Hīnayāna; 7. Contrast with the powers and fearlessnesses to clarify distinctions, roots, and branches.
