大乘起信論義記 2.196

2.196

猶如迷人依方故迷，若離於方則無有迷。眾生亦爾，依覺故迷，若離覺性則無不覺。

“It is just like a lost person who is confused dependent on direction; if one were separated from direction, there would be no confusion. Sentient beings are also like this: they are confused dependent on enlightenment; if they were separated from the nature of enlightenment, there would be no non-enlightenment.”
