大乘起信論略述 1.107

1.107

論。眾生亦爾至則無不覺　述曰。此法合也。本覺真性如正方所。根本不覺似能迷人。心業等動念是如邪方。如離正東無別邪西。故言若離覺性即無不覺。然此不覺與前本覺雖非一異。不離覺性。雖不離覺。非即覺性。

[Treatise:] Sentient beings are also like this... then there would be no non-awakening.
[Commentary:] This is the application of the dharma. The real nature of original awakening is like the correct direction. Fundamental non-awakening resembles the lost person. The movements of thought such as the activity of the mind resemble the wrong direction. Just as, apart from the true east, there is no separate false west, so it says, “if one were separated from the nature of awakening, there would be no non-awakening.” However, although this non-awakening and the preceding original awakening are neither one nor different, it is not separate from the nature of awakening; and though not separate from awakening, it is not identical with the nature of awakening.
