金剛般若經旨贊 2.28

2.28

經。爾時至如是之經　贊曰。此善現悲對也。聞捨多身不如經福。領解此經為菩提因。深妙理趣法喜之極感激生悲。謂我昔得見道真智契證無為。雖名惠眼未曾聞是希有之法。即義中法門希有。准餘本經。此下更有何以故佛說般若波羅蜜即非般若波羅蜜。即七義中法門。第一頌中上義智岸難量。釋此文也。何以故者。徵不聞之所以。佛說已下釋不聞之所以。此智岸有二種義故。雖惠眼而未聞也。一是智岸勝上義故。故云佛說般若波羅蜜。二以智岸難測量故。故云即非般若波羅蜜。由斯二義特異餘經故。總說為法門第一。

Sūtra: At that time, [...] such a sūtra. / Commentary: This is Subhūti's sorrowful response. Having heard that renouncing many bodies does not equal the sūtra's merit, he grasped that this sūtra is the cause of bodhi; at the utmost peak of the profound, marvelous principle and Dharma joy, he was deeply moved and gave way to tears of sorrow. He thought: "Formerly, when I attained the true wisdom of the path of seeing and realized the unconditioned, though I was called possessor of the wisdom-eye, I had never heard such a rare dharma." This refers to the rareness of the dharma-door among the [seven] meanings. According to other recensions of the sūtra, below this there is further: "Why is this? The prajñāpāramitā spoken of by the Buddha is precisely non-prajñāpāramitā." This is the first of the seven meanings: the dharma-door. In the verse, "the supreme meaning, the shore of wisdom hard to fathom" explains this passage. "Why is this?" questions the reason for not having heard it. "The Buddha spoke of..." and below explains the reason for not having heard it. Because this shore of wisdom has two meanings, even with the wisdom-eye he had not heard it: first, because it is the superior, supreme meaning of the shore of wisdom, hence it says "the Buddha spoke of prajñāpāramitā"; second, because the shore of wisdom is hard to fathom, hence it says "is precisely non-prajñāpāramitā". Because of these two meanings it is distinctly different from other sūtras, so it is generally spoken of as the supreme dharma-door.
