瑜伽論記 12.167

12.167

言謂於一切近稠林行者，此總舉十一稠林，如心行等十一稠林即是菩薩所觀境也。如此雜染，如此清淨者，是心行稠林也，即染淨心行故，由此雜染者即是煩惱稠林業行稠林。由此清淨者是根行稠林，謂信等五根也。若所雜染者，若所清淨者謂信行稠林，即是勝解，若與煩惱相應名所雜染，若與清淨法相應若所清淨。若非一向者說性行相稠林深心行相稠林，是菩薩所觀，或是有性或是無性非一向也。若是一向者是使行稠林心生行稠林，謂諸屬煩惱一向染故，菩薩息苦等五生是清淨故之言一向也。

As for the statement "namely, regarding all activities bordering on thickets": this broadly brings up the eleven thickets; the eleven thickets, such as mental activity, are precisely the objective spheres contemplated by the bodhisattva. "Such defilement, such purification": this is the thicket of mental activity, meaning the defiled and pure mental activities. "Defiled by this": this is the thicket of afflictions and the thicket of karmic activity. "Purified by this": this is the thicket of faculty activity, namely the five faculties of faith and so forth. "What is defiled, what is purified": this refers to the thicket of faith activity, which is adhimokṣa; if conjoined with afflictions it is called "what is defiled," and if conjoined with pure dharmas it is "what is purified." "If not one-sided": this speaks of the thicket of the characteristics of nature activity and the thicket of the characteristics of profound disposition activity; they are what is contemplated by the bodhisattva, and being either with nature or without nature, they are not one-sided. "If one-sided": this is the thicket of latent tendency activity and the thicket of mental birth activity, meaning that all belonging to afflictions are exclusively defiled, while the five births of the bodhisattva, such as pacifying suffering, are pure; hence the phrase "one-sided."
