法華義疏 4.172

4.172

肉、慧兩眼就體得名，以肉為眼故名肉眼，以慧為眼故名慧眼也。法眼則從境立名，以其見法名為法眼、天眼、佛眼得名不定，所以然者，天眼得名凡有三種：一、從人立稱，又從義得目。諸佛菩薩名為淨天，生在人中報得眼根徹見大千世界，從彼淨天以立其名故名天眼。二者、就趣得名。始從四王上至非想通是天趣，生彼天中報得眼根，能遠照矚，故名天眼。三者、從因受名。如《地持》說，一切禪定於三住中名為天住，依此天住修得淨眼，從因得名故云天眼。佛眼得名凡有二種：一、從人得名，佛是人名，人有此眼故名佛眼；二、佛名覺，則此覺能照故名為佛眼。

The flesh and wisdom eyes receive their names based on their substance: using flesh as the eye, it is called the flesh eye; using wisdom as the eye, it is called the wisdom eye. The Dharma eye derives its name from its object: because it sees phenomena (dharmas), it is called the Dharma eye. The divine eye and the Buddha eye do not have a fixed way of receiving their names. The reason is that the divine eye receives its name in three ways: First, the designation is established based on the person, and its title is also derived from its meaning. Buddhas and bodhisattvas are called pure devas; born among humans, they obtain as a karmic recompense an eye faculty that sees clearly throughout the trichiliocosm; deriving its name from those pure devas, it is called the divine eye (deva eye). Second, it receives its name based on the destiny. From the Four Heavenly Kings up to the Sphere of Neither Perception Nor Non-Perception, all are generally the divine destiny; born in those heavens, they obtain as a karmic recompense an eye faculty capable of distant illumination, and hence it is called the divine eye. Third, it receives its name based on its cause. As the Dichi lun says, all dhyānas among the three abidings are called divine abidings; cultivating and obtaining a pure eye in reliance on these divine abidings, it receives its name from its cause, and thus is called the divine eye. The Buddha eye receives its name in two ways: First, it receives its name from the person: 'Buddha' is a designation for a person, and because that person possesses this eye, it is called the Buddha eye. Second, 'Buddha' means awakening; thus, because this awakening is capable of illuminating, it is called the Buddha eye.
