瑜伽師地論略纂 2.4

2.4

Regarding the ten gates, the verse below says: "Clusters of matter, associated categories, temporal characteristics and conditions, the gates of distinction such as wholesome, and finally the matters of skillful means." Within the distinctions such as wholesome, there are three gates: first, the three natures; second, the numerical progression of the twelve āyatanas; third, explaining the names and meanings of the twelve āyatanas. Within matter, there are two parts: first, marking; next, explaining. The explanation is divided into seven: first, clarifying that the primary elements serve as five causes in producing matter; second, clarifying the distinction between the existence and nonexistence of paramāṇus; third, clarifying that the primary elements and derived matter do not exist separately; fourth, clarifying the quantity of matters in material clusters; fifth, clarifying the continuity and interruption of various forms of matter; sixth, clarifying the distinctions among the three kinds of material clusters; seventh, clarifying that material clusters function based on the six bases.
