大乘起信論義記 3.179

3.179

問曰：上說真如，其體平等，離一切相，云何復說體有如是種種功德？答曰：雖實有此諸功德義，而無差別之相，等同一味，唯一真如。此義云何？以無分別離分別相，是故無二。

"Question: It was said above that tathatā's substance is equal and free from all marks; why is it said again that the substance has such various virtues? Answer: Although it truly has the meanings of these various virtues, there are no marks of differentiation; they are equal and of one taste, solely the one tathatā. What does this mean? Because it is without discrimination and free from the marks of discrimination, therefore it is non-dual."
