俱舍論頌疏論本 25.48

25.48

釋曰：加行道者，謂引無間道前之加行也。無間道者，謂諸斷惑道也。解脫道者，無間道後名解脫道，謂已解脫所應斷障。最初所生勝進道者，除前三外，所餘諸道漸勝進故，即解脫道後所起諸道也。問：「道義云何？」答：「謂涅槃路，乘此能往涅槃城故。又解：道者，謂求所依，依此尋求涅槃果故。」

Explanation: The preparatory path refers to the preparation that precedes and induces the uninterrupted path. The uninterrupted path refers to the paths that sever defilements. The path of liberation is that which follows the uninterrupted path, meaning that one has already been liberated from the hindrance that was to be severed. The superior advancement path, which arises initially, refers to all remaining paths apart from the first three that progressively advance higher; that is, the various paths that arise after the path of liberation. Question: "What is the meaning of 'path'?" Answer: "It means the road to nirvāṇa, because by mounting this one can go to the citadel of nirvāṇa. Another explanation: 'path' means the basis of seeking, because based on this one seeks the fruition of nirvāṇa."
