成唯識論述記 10.610

10.610

述曰：次，三、解常。此又是常，五法俱無盡期故。又，真如無生滅故常，無變易故常，皆自性常故。四智心品所依真如常，故常。其四智品體無斷及無盡，故說常。無斷常者，是不斷常義，報身也；無盡常者，是化身，相續常義。《莊嚴論》說三種常故，如常施食、受樂等事，四智「非自性常」義。「從因所生」者，謂明從種生故。若初唯生後不滅者，便違佛說，一向記言：生者皆滅故。又若色、心是自性常者，不見說故，違比量故。獲得常色等者，由願力化有情，是不斷相續常義。七十八、《解深密》說：化身有生起相故。「窮未來際」，亦釋不斷、無盡常義，願力常故。餘文可解。

The Commentary states: Next, the third [characteristic] explains "eternal" (nitya). This is also eternal because all five dharmas have no ending point. Moreover, tathatā is eternal because it has neither arising nor ceasing; it is eternal because it is without change—both being eternal by intrinsic nature (svabhāva-nitya). Because the tathatā upon which the mental categories of the four cognitions rely is eternal, they are eternal. The substance of the four categories of cognition is uninterrupted and endless; therefore, they are said to be eternal. The eternal as non-interruption means the sense of eternal without break, which is the enjoyment body (saṃbhogakāya); the eternal as endlessness is the transformation body (nirmāṇakāya), in the sense of an eternal continuum. Because the Mahāyānasūtrālaṃkāra explains three kinds of eternity—like the continuous giving of food or experiencing of pleasure—the four cognitions are "not eternal by intrinsic nature". "Born from causes" clarifies that they arise from seeds (bīja). If they only arose at the beginning and never ceased thereafter, this would contradict the Buddha's definitive declaration: all that arises ceases. Furthermore, if form and mind were eternal by intrinsic nature, this is never stated [in scripture], and it contradicts inference (anumāna). Attaining eternal form and the like means that through the power of vows one transforms sentient beings, which is the sense of an uninterrupted, continuous eternity. Fascicle seventy-eight [of the Yogācārabhūmi] and the Saṃdhinirmocana-sūtra state that the transformation body exhibits marks of arising. "Exhausting the bounds of the future" also explains the meaning of uninterrupted and endless eternity, for the power of vows is eternal. The remaining text is easy to understand.
