起信論疏筆削記 14.54

14.54

論　無有自性，四、無性有體對。疏　妄染無體者，依真妄動，何有自體？淨心者，心無動故，離緣獨立。獨立之體本來無染，斯則不逐緣生、不因境起，故云自性清淨心也。

The treatise states: "Having no self-nature..."—fourth, the pairing of lacking nature versus possessing essence. The commentary states: "Deluded defilement has no essence..."—moving deludedly in reliance on the true, how could it have its own essence? "The pure mind"—because the mind has no movement, it stands alone, free from conditions. This independently standing essence is originally undefiled; thus it does not arise following conditions and does not occur due to objects, and is therefore called "the intrinsically pure mind."
