首楞嚴義疏注經 3.117

3.117

Refuting its being born from the faculty. The first part cites [the assertion]; from "what is said to be born from the nose" onward is the direct refutation; from "as for your" onward is the conditional refutation. Even granting that your nose could generate fragrance, although the sense of generation would be established, the sense of smelling would not stand, because it would merely emit fragrance and not enter from outside to unite with the nose.
