中觀論疏 7.16

7.16

「諸行亦如是」下，第五觀行。然五陰次第，行在第四，但此品既稱觀行，欲廣破之，故迴在第五。就文為三：第一明身口意三行；「有二種」下，第二明淨不淨二行；「或增或減」下，第三明行增減義。就文為三，謂法、譬、合。初是法說。行陰乃含多法，今正取造善惡業名之為行。業能感果，故名為增；受報極則減，故名為減。「如人有病」下，第二喻說，還喻上增減之義。「諸行亦如是」下，第三合喻。以明增減不定，是故行空也。

From "All formations are also like this" onwards is the fifth [section], contemplating formations (saṃskāra). Although in the sequence of the five aggregates formations are the fourth, this chapter is named "Contemplating Formations"; wanting to refute them extensively, [the author] places them fifth. The text has three parts: first, explaining the three formations of body, speech, and mind; second, from "There are two kinds" onwards, explaining the two formations of pure and impure; third, from "Or increasing or decreasing" onwards, explaining the meaning of the increase and decrease of formations. The text comprises three parts, namely the statement of doctrine, the simile, and the application of the simile. The first is the statement of doctrine. The aggregate of formations contains many phenomena, but here it specifically takes the creating of good and evil karma and calls it "formations". Karma can induce retribution, and is therefore called "increasing"; when the experiencing of retribution reaches its limit, it diminishes, and is therefore called "decreasing". From "Just as a person has an illness" onwards is the second [part], the simile, which illustrates the aforementioned meaning of increase and decrease. From "All formations are also like this" onwards is the third [part], the application of the simile. By showing that increase and decrease are unfixed, formations are therefore empty.
