大乘起信論略述 1.52

1.52

論。此義云何至不相離故　述曰。此釋成也。此云何者。二門若別不合相。從如本一心未容皆攝。如何二門各總攝邪。故次答云。以是二門不相離故。以真如門是心理體。生滅門者是心事相。以彼理事不相離故。舉理攝事。舉事攝理。故說二門皆各總攝。

[Treatise:] What does this mean? […] because they are not separated. [Exposition:] This explains and establishes it. "What does this mean?": If the two aspects were separate, they should not follow each other; like the original one mind, they would not yet allow for gathering all. How could each of the two aspects comprehensively gather? Therefore, it replies next: "Because these two aspects are not separated." Because the aspect of suchness is the principle-essence of the mind, and the aspect of arising and ceasing is the phenomenal-characteristics of the mind. Because principle and phenomena are not separated, taking up principle gathers phenomena, and taking up phenomena gathers principle. Therefore, it is said that the two aspects each comprehensively gather [all dharmas].
