金剛經纂要刊定記 6.29

6.29

佛具下。或問曰：「佛為至聖，何以同凡有肉眼耶？」故此通之。然但約具諸根處說有肉眼，非謂如來是血肉身。故經云：「捨無常色，獲常色等。」

"The Buddha possesses," and so forth: someone might ask, "Since the Buddha is the supreme sage, why would he share the physical eye with ordinary persons?" Therefore this clarifies it: however, it is only said that he possesses the physical eye in terms of his having all faculties complete; it does not mean that the Tathāgata has a body of blood and flesh. Hence the sūtra says: "Having renounced impermanent matter, he attains permanent matter, and so forth."
