起信論疏筆削記 20.2

20.2

觀中，論　心沈沒者，以真如無相，向即心絕，分別不起，故云沈沒。此如二乘取空為證也，由沈寂故遂成二失，如下列釋。論　或起下，正顯失。

Under "Contemplation," the Śāstra says: "The mind sinks down": because tathatā is markless, when one turns toward it the mind is severed and conceptual differentiation does not arise; hence it is said to "sink down." This is like the two vehicles grasping emptiness as realization. Because of sinking into stillness, two faults eventually occur, as listed and explained below. In the Śāstra, from "or arising" downward directly reveals the faults.
