金剛般若經贊述 2.158

2.158

又論云，「於中略說有四種眼，謂色攝、第一義諦攝、世諦攝、一切種一切應知攝。色攝復有二種，謂法果、修果，此為五眼麁境界故，是初色攝」。解云，肉、天二眼，色根為性，謂淨色四大所造；或異熟長養，說名肉眼，此謂法果也，此通餘界及四禪。若修禪除擁而得者，此謂修果也，唯四禪地有，謂於諸色內外、兩邊、裏表、上下皆悉能見也。

The commentary also states: "Among these, briefly speaking, there are four kinds of eyes: subsumed under form, subsumed under the paramārthasatya, subsumed under saṃvṛtisatya, and subsumed under all modes of all that should be known. That which is subsumed under form again has two kinds: the fruition of dharma and the fruition of cultivation. Because these are the coarse objects of the five eyes, they are the first, subsumed under form." The explanation says: The physical and divine eyes have material sense faculties as their nature, meaning they are composed of the pure material four great elements; or else, produced by ripening and nourishment, it is called the physical eye—this is called the fruition of dharma, and it extends to the other realms and the four dhyānas. If it is attained by cultivating dhyāna to remove obstructions, this is called the fruition of cultivation; it exists only in the grounds of the four dhyānas, meaning that with respect to all forms, internally and externally, on both sides, inside and outside, above and below, it is able to see all of them.
