觀心論疏 4.9

4.9

問：生死眾生有佛法界十如，經論明證理應可信。但佛是出生死人，何得復有六道法界十如耶？答：斯義微隱，實難可取信。經云「五眼具足成菩提」，又佛問須菩提：「佛有肉眼不，乃至問有佛眼不」，答云：「有」。然既有凡夫之肉眼，豈無凡夫之六根？是即肉眼、天眼及六根即是六道法界，慧眼即二乘法界，法眼即菩薩法界，佛眼即佛界。斯則佛既具五眼，則有十法界百如明矣。

Question: That sentient beings in birth-and-death possess the ten suchnesses of the Buddha-dharma-realm has clear evidence in the sūtras and treatises, and the principle should indeed be believable. But the Buddha is a person who has transcended birth-and-death; how could he also possess the ten suchnesses of the dharma-realms of the six destinies? Answer: This meaning is subtle and hidden, and truly difficult to place faith in. The sūtra says: "Complete with the five eyes, one achieves bodhi." Furthermore, the Buddha asked Subhūti: "Does the Buddha possess the physical eye or not?" up to asking whether he possesses the Buddha eye or not, and [Subhūti] answered: "He does." Thus, since he possesses the physical eye of an ordinary being, how could he lack the six sense faculties of an ordinary being? These being so, the physical eye, the divine eye, and the six sense faculties are themselves the dharma-realms of the six destinies; the wisdom eye is the dharma-realm of the two vehicles; the dharma eye is the bodhisattva dharma-realm; and the Buddha eye is the Buddha-realm. Thus, since the Buddha is endowed with the five eyes, it is clear that he possesses the ten dharma-realms and the hundred suchnesses.
