大方廣圓覺修多羅了義經略疏 1.794

六根門中根、識、塵三各有分界故，亦是因義、種族義故。前為六二，解者息於業因。此是六三，觀之治於我執。兼之五蘊即具三科。大小乘宗無不約此以明諸義。前說妄認四大身心，及云中外合成等，即五蘊義，故此略之。

Within the gates of the six faculties, the three of faculty, consciousness, and dust each have their distinct boundaries, and also because it has the meaning of cause and the meaning of lineage (gotra). The preceding is the six sets of two; one who understands rests from the causes of karma. Here it is the six sets of three; contemplating it remedies grasping to a self. Combined with the five aggregates, they complete the three categories. The Mahāyāna and Hīnayāna traditions without exception rely on these to explain all meanings. The previous discussion of falsely identifying the four elements as body and mind, and saying that they are combined internally and externally, precisely constitutes the meaning of the five aggregates; hence it is omitted here.
