論三者分別智相應染依具戒地漸離乃至無相方便地究竟離故　述曰。即五意中名為智識。念慮染淨名分別智。猶分別此則是淨此則是染。故曰慮也。亦分別智污淨心故名之為染。從第二地至第六地入觀緣理分別時。分分能除故云漸離。若至七地長時入觀故此法執永不現行。猶數數須作意不作則恐失念。猶有作意法執在未能得任運。故曰法執也。第三地猶有分別染淨此則淨法此則染法。此分別智也。問。離何分別。只離分別此則是法此則是染法。到第六地入觀緣理離分別時故分分能除。故云漸離。若至七地長時入觀故此法永不現行。名究竟離。具戒地者即第二地。此地具足三聚淨戒。何三聚淨戒。答。為第三卷經性戒他不犯也。故無相方便即第七地。常作意住無相觀故。

[Treatise:] Third is defilement associated with discriminating cognition, which is gradually abandoned relying on the stage of possessing the precepts, up to the stage of signless expedient means, where it is ultimately abandoned. [Commentary:] This is called the discriminating consciousness among the five minds. Thinking and deliberating on the defiled and the pure is called discriminating cognition. It is like discriminating: "this is pure, this is defiled"; hence it is called deliberating. Also, discriminating cognition pollutes the pure mind, so it is called defilement. From the second stage to the sixth stage, when entering contemplation to observe the principle and discriminate, it can be eliminated portion by portion; hence it says "gradually abandoned." When reaching the seventh stage, because of entering contemplation for long durations, this attachment to dharmas never becomes manifest. Still, one must frequently apply attention; if one does not, there is fear of losing mindfulness. Still possessing the attachment to dharmas of intentional attention, one is not yet able to attain spontaneity; hence it is called attachment to dharmas. In the third stage, one still discriminates defilement and purity: "this is a pure dharma, this is a defiled dharma"—this is discriminating cognition. Question: What discrimination is abandoned? One only abandons discriminating: "this is a [pure] dharma, this is a defiled dharma." Reaching the sixth stage, when entering contemplation to observe the principle and abandon discrimination, it can be eliminated portion by portion; hence it says "gradually abandoned." When reaching the seventh stage, because of entering contemplation for long durations, this dharma never becomes manifest, which is termed "ultimately abandoned." The "stage of possessing the precepts" is the second stage. This stage is replete with the three collections of pure precepts. What are the three collections of pure precepts? Answer: As stated in the third fascicle of the sūtra, it is the natural morality not violated by others. Thus "signless expedient means" is the seventh stage, because one constantly applies attention to abide in signless contemplation.
