維摩經玄疏 4.14

4.14

三、正因理心發者，眾生無始以來，佛性真心常為無明之所隱覆，緣、了兩因力破無明暗，豁然圓顯也。

Third, as for the generation of the principled mind of direct causes: the true mind of buddha-nature that has been hidden and covered by ignorance in sentient beings since beginningless time is, through the power of the two causes of conditioning and revealing, shattered in its darkness of ignorance and suddenly and perfectly revealed.
