首楞嚴義疏注經 2.183

2.183

佛具五眼三智，所見窮盡法界。已上四位階級所見，淺深不同。蓋真見之用隨證所得，漸明漸遠也。

The Buddhas possess the five eyes and the three knowledges; what they see exhaustively encompasses the dharmadhātu. The above four levels of stages see with varying degrees of shallowness and depth. The function of true seeing, according to what is attained through realization, becomes gradually brighter and reaches gradually farther.
