大乘起信論略述 2.109

2.109

論。若如來藏至無是處故　述曰。此返破也。謂諸聖者證會此時既離妄染故。如來藏體無妄也。

[Treatise:] "If the Tathāgata-garbha [had defilements and we said it causes one to eradicate them, there could be no such thing]..." [Commentary:] This turns back to shatter [the attachment]. It means that when the noble ones realize and integrate with this, they are already free from deluded defilement; therefore, the essence of the Tathāgata-garbha is devoid of delusion.
