21.73

斷彼能緣故者，第二因也，此名斷彼能緣故斷，謂見苦、集，斷他界緣，以自界緣惑緣他界緣惑，他界緣惑是所緣境，自界緣惑是能緣心也。若斷自界緣惑時，彼他界緣惑即隨斷，名斷彼能緣故斷。言能緣者，即自界緣是也。

As for 'through abandoning their cognizing subjects', this is the second cause; this is called abandonment through abandoning their cognizing subjects. It refers to abandoning [the afflictions with] objects of other planes by seeing suffering and the origin, because the afflictions with objects of one's own plane take as their objects the afflictions with objects of other planes: the afflictions with objects of other planes are the objective spheres cognized, and the afflictions with objects of one's own plane are the cognizing minds. When the afflictions with objects of one's own plane are abandoned, those afflictions with objects of other planes are abandoned along with them, which is called abandonment through abandoning their cognizing subjects. The words 'cognizing subjects' refer precisely to those [afflictions with] objects of one's own plane.
