gandha-matram abhut tasmat
prthvi ghranas tu gandhagah
rasa-matrat—which evolves from the subtle element taste; vikurvanat—undergoing transformation; ambhasah—from water; daiva-coditat—by a superior arrangement; gandha-matram—the subtle element odor; abhut—became manifest; tasmat—from that; prthvi—earth; ghranah—the olfactory sense; tu—in fact; gandha-gah—which perceives aromas.
Due to the interaction of water with the taste perception, the subtle element odor evolves under superior arrangement. Thence the earth and the olfactory sense, by which we can variously experience the aroma of the earth, become manifest.
