首楞嚴義疏注經 10.6

10.6

圓明心體，名為覺明。離想浮動，故名虛靜。空喻覺明，晴喻離想，麁重即煩惱也，以想陰是煩惱濁故。前塵影事，即所想境。能想既亡，所想不立，故云無復。

The perfectly clear mental substance is called 'cognitive clarity'. Free from the agitation of conception, it is called 'empty and serene'. The sky illustrates cognitive clarity; the clear weather illustrates being free from conception; 'coarse and heavy' refers to afflictions, because the aggregate of conception is the turbidity of affliction. The 'shadowy matters of the previous dusts' are the objects conceived. Since the conceiving subject is gone, the conceived objects do not stand; hence it says 'no longer having'.
