大乘起信論裂網疏 4.37

4.37

"Answer: Although all sentient beings equally possess tathatā, yet from time without beginning, the thickness or thinness of ignorance and their intrinsic distinctions exceed the sands of the Ganges; the binding afflictions such as self-view and craving are also like this. Only the wisdom of the Tathāgata can know them; therefore, faith and so forth have distinctions of earlier and later."
