起信論疏筆削記 14.55

14.55

論　非常下，五、顛倒真實對。疏　四倒者，即無常、苦、無我、不淨。心動故起於有漏色心，有漏色心實非常等，凡夫計為常等，故成四倒。反之等者，以不動故，色心不起。以不起故，唯真如性，常住清淨，自在安樂，故成四德。

The treatise states: "Not permanent..." onward—fifth, the pairing of inverted versus true. The commentary states: "The four inversions..."—namely, impermanence, suffering, non-self, and impurity. Because the mind moves, it gives rise to contaminated matter and mind; contaminated matter and mind are truly not permanent, etc., but ordinary beings conceptually grasp them as permanent, etc., thus forming the four inversions. "Contrasting with it..." onward—because of being unmoving, matter and mind do not arise. Because they do not arise, there is only the nature of tathatā, permanently abiding, pure, sovereign, and peacefully blissful; thus forming the four virtues.
