成唯識論了義燈 2.69

2.69

論非顯香味。量云：汝顯色及香、味應非是表；唯無記故；如地、水、火。雖自宗有香、味通表，而是假表，不通善、惡，意為破他實表業色，復是善、惡。彼自許香、味、觸三唯無記故，又准論疏應云：汝此表色，亦非是顯，及與香、味，無表示故如觸，是彼許故。

The treatise negates color, odor, and taste. The logical argument is: "Your color-form, as well as odor and taste, should not be intimation (vijñapti); because they are solely indeterminate; like earth, water, and fire." Although in our own school odor and taste do admit of intimation, it is nominal intimation and does not extend to good or evil; the intention is to refute the other's real intimation of bodily action (kāyavijñapti), which furthermore is good or evil. They themselves admit that odor, taste, and touch are solely indeterminate. Furthermore, following the treatise commentary, one should say: "Your intimation-form is also not color, nor odor or taste; because it lacks manifestation, like touch"; this is because they admit it.
