風神ヴāユは言った。「かくして地の香（物質の匂い）は十種と知るべきである。好ましき香（芳香）と好ましからぬ臭（悪臭）；甘・酸・辛；遠くまで広がる香；混じり合う香；潤い油のごとき香；乾いた香；そして清らかに明らかな香。これらが地より生ずる匂いの十種であり、識別すべきである。」

Educational Q&A
The verse classifies the earth-element’s sensory property—smell—into ten recognizable types, training discernment of material qualities as part of a broader philosophical/educational exposition.
Vāyu-deva is speaking in a didactic context, enumerating and defining categories of ‘earthly odor’ to instruct the listener in the analysis of elemental and sensory properties.
