大乘起信論略述 2.16

2.16

[Treatise:] Because cause and condition are both [...] accomplishes natural activity. [Commentary:] This reveals the realization of principle. "Cause" refers to avidyā. "Condition" refers to deluded objects. "Marks of the mind" refers to the coarse and subtle defiled minds. Because these are all exhausted, the essence of the mind undergoes transformation of the basis; this is called attaining nirvāṇa and accomplishing natural activity. Transformation of the basis has two kinds: first, transformation of manifestation—that is, because the essence of the mind is manifested through the cause of comprehension, it is called attaining nirvāṇa; second, transformation of acquisition—that is, because the function arises through the generative cause, it accomplishes natural activity.
