首楞嚴義疏注經 5.212

5.212

六塵生滅是意家境。今觀此法，本自不生、今則無滅，以心生故種種法生、心滅故種種法滅，心不見心，無相可得，能所都寂，法性現前。身之與心本來不動，故令能度多劫如彈指也。

The arising and ceasing of the six dusts is the domain belonging to the mind. Now, contemplating these dharmas as originally unarisen and presently without cessation: because mind arises, manifold dharmas arise; because mind ceases, manifold dharmas cease. Mind does not see mind, and there are no marks to be apprehended; subject and object are both tranquil, and the dharma-nature manifests before one. The body and mind are originally unmoving, and therefore enable one to pass through many kalpas as if in a snap of the fingers.
