成唯識論述記 3.760

3.760

述曰：「所知」者，即三性與彼為依，名「所知依」，即《攝論》第一〈所知依品〉是。此「所知依」，阿賴耶識之別名也，故《中邊》云：「虛妄分別有，於此二都無，此中唯有空」，是故三性法，皆依此識有。

The Commentary states: 'The knowable' refers to the three natures (trisvabhāva); because it serves as the support for them, it is called 'the basis of the knowable' (jñeyāśraya), which is precisely the chapter 'The Basis of the Knowable' in the first fascicle of the Mahāyānasaṃgraha. This 'basis of the knowable' is an alternate name for the ālayavijñāna. Thus the Madhyāntavibhāga says: 'False discrimination exists; duality does not exist in it; in this there is only emptiness.' Therefore, the dharmas of the three natures all exist relying on this consciousness.
