首楞嚴義疏注經 10.329

10.329

「阿難當知，此湛非真，如急流水，望如恬靜，流急不見，非是無流。若非想元寧受妄習？非汝六根互用合開，此之妄想無時得滅。」

"Ānanda, you should know that this tranquility is not real. It is like a swift current that looks serene from afar; the flow is so rapid that it is invisible, yet it is not that there is no flow. If it were not the source of thought, how could it receive habitual delusion? Unless your six sense faculties function interchangeably, combining and opening, this false thought will never be extinguished.
