大乘義章 20.15

20.15

次第七門辨定其因。五眼之因有通有別。通而論之，一切諸行悉共得之。故《大品》云「菩薩修學波若波羅蜜淨於五眼。」波若既然，餘行皆爾。何故不言生於五眼，乃云淨乎？龍樹自釋「菩薩之人先有肉眼，亦有四眼，分結使覆故不得淨。如鏡性明，垢故不見。若除其垢，照明如本。如彼天眼慧眼法眼及以佛眼，非是新起，故不名生。本有今顯，故但言淨。」以斯准驗，佛德本有，義在不虛。蓋一相言，於中分別，亦有生義。通相如是。若別論之，布施燈明淨物因緣得於肉眼，持戒禪定因緣力故得於天眼，持戒因緣得於欲界有報天眼，禪定因緣得色界上一切天眼，修習無量淨慧因緣得餘三眼。又論宣說「修習無量功德智慧，得餘三眼。」

Next, the seventh section determines their causes. The causes of the five eyes have general and specific [aspects]. Discussing them generally, all practices jointly obtain them. Therefore the Pañcaviṃśati says: "The bodhisattva's cultivation and study of prajñāpāramitā purifies the five eyes." Prajñā being so, the other practices are all likewise. Why does it not say 'generates the five eyes', but instead says 'purifies'? Nāgārjuna himself explains: "The bodhisattva originally possesses the flesh eye, and also possesses the [other] four eyes, but because they are obscured by fractions of defilements, they do not attain purity. Just as a mirror is luminous by nature, but due to grime it does not see; if one removes its grime, its illumination is as of old. Like that, the divine eye, wisdom eye, Dharma eye, and Buddha eye are not newly arisen, hence they are not termed 'generated'. What is originally possessed is now revealed, hence it only says 'purifies'." Taking this as verification, the Buddha-virtues are originally possessed, a meaning that is not false. This is a single-aspect statement; if distinguished within it, there is also the sense of generation. Such is the general aspect. Discussing them specifically: through the causal conditions of giving lamps and clean items, one obtains the flesh eye; through the power of the causal conditions of observing precepts and dhyāna, one obtains the divine eye; through the causal condition of observing precepts, one obtains the retributive divine eye in the desire realm; through the causal condition of dhyāna, one obtains all divine eyes in the form realm and above; through the causal conditions of cultivating immeasurable pure wisdom, one obtains the remaining three eyes. Furthermore, the treatise states: "By cultivating immeasurable merit and wisdom, one obtains the remaining three eyes."
