首楞嚴義疏注經 4.519

4.519

「由通、塞等二種相發，於妙圓中粘湛發嗅，嗅精映香，納香成根，根元目為清淨四大，因名鼻體。如雙垂爪，浮根四塵流逸奔香。」

"Due to the two kinds of mutual stimulation, such as openness and blockage, within the wondrously perfect [nature] it adheres to the still clarity and generates smelling. The essence of smelling reflects upon fragrance, absorbing fragrance to become a faculty. The root of the faculty is designated as the pure four great elements, and is therefore named the body of the nose. Resembling a pair of hanging claws, the four dusts of the floating faculty drift out and rush after fragrance."
