俱舍論記 17.29

17.29

「如是說者至名斷善根」者，此即正義，漸斷善根。所斷九品善根，從麁至細名逆；能斷九品邪見，從細至麁名順。逆順相對漸次而斷，如修道斷修所斷惑，九品漸斷。若作斯釋，符本論文。彼論既言「微俱行善是最後捨」，明知善根九品漸斷。

Regarding "The correct doctrine says ... is called severing the wholesome roots": This is the correct doctrine: the wholesome roots are severed gradually. The nine grades of wholesome roots to be severed, moving from coarse to subtle, are called the "reverse"; the nine grades of wrong view capable of severing, moving from subtle to coarse, are called the "direct." Corresponding in reverse and direct, they are severed sequentially, just as the defilements abandoned through cultivation are abandoned in the path of cultivation—the nine grades are severed gradually. If one gives this explanation, it accords with the root treatise. Since that treatise says, "The subtle concurrent wholesome is abandoned last," we clearly know that the wholesome roots are severed gradually in nine grades.
