首楞嚴義疏注經 4.528

4.528

"Due to the two kinds of mutual continuity, such as arising and ceasing, within the wondrously perfect [nature] it adheres to the still clarity and generates cognition. The essence of cognition reflects upon dharmas, gathering dharmas to become a faculty. The root of the faculty is designated as the pure four great elements, and is therefore named the mental faculty. Resembling seeing in a dark chamber, the four dusts of the floating faculty drift out and rush after dharmas."
