大乘起信論義疏 1.67

1.67

自下第二釋「心生滅門」，此中有二：一者略表其體；二「此識有二」以下廣說其義。「心生滅者」，顯名也。「依如來藏」者，是第八識也。「有生滅心」者，是第七識也。此言依者，同時相依，如影依形。此之二句，妄有所以。此妄之中隨妄轉流，名第八識。下正表體，有三句：所謂「不生不滅」者，其體常住，隨緣成妄，而體非無常，如上說也。此之一句正表體常，「與生滅和合」者，隨緣令妄和合如一。此之一句明隨妄義。「非一」者，性常住故；「非異」者，令和合故。此之二句辨隨緣相。以此三句辨第八識也。「名阿梨耶識」者，是梵語也，此翻名為無失沒識。雖在生死，性不失沒，故名無沒。名隨義翻，名為宗識。妄所依故，亦名藏識，備有一切諸淨法故。此等名者經論非一，而非正翻也。

From here below, the second [part] explains the "gate of the mind arising and ceasing". Here there are two: first, a brief presentation of its substance; second, from "This consciousness has two" downward, an extensive explanation of its meaning. "The mind arising and ceasing" reveals the name. "Relying on the tathāgatagarbha" refers to the eighth consciousness. "There is the mind that arises and ceases" refers to the seventh consciousness. The word "relying" here means simultaneous mutual reliance, like a shadow relying on a form. These two phrases give the reason for the existence of delusion. Within this delusion, flowing and revolving in accordance with delusion, it is named the eighth consciousness. Below, directly presenting the substance, there are three phrases: what is called "neither arising nor ceasing" means that its substance is permanently abiding; conforming to conditions it forms delusion, yet its substance is not impermanent, as explained above. This single phrase directly presents the permanence of the substance. "Combining with arising and ceasing" means that conforming to conditions it causes delusion to combine into one. This single phrase explains the meaning of conforming to delusion. "Not one" is because its nature is permanently abiding; "not different" is because it causes them to combine. These two phrases distinguish the characteristics of conforming to conditions. With these three phrases, the eighth consciousness is distinguished. "Named the ālaya consciousness (ālayavijñāna)": this is Sanskrit, translated here as the "consciousness without loss or lapse". Although within saṃsāra, its nature is not lost or lapsed, hence it is called "without lapse". Translating according to its meaning, it is called the "fundamental consciousness". Because it is what delusion relies upon, it is also called the "storehouse consciousness" (ālayavijñāna), because it is fully endowed with all pure phenomena. These names are more than one across the sūtras and treatises, yet they are not standard translations.
