Vāyu-deva said: “Sound, touch, form, taste, and as the fifth, smell—these five are to be understood as the qualities of the earth, O best of the twice-born, O foremost brāhmaṇa.”
वायुदेव उवाच
Earth (bhūmi) is characterized by five sensory qualities—sound, touch, form, taste, and smell—presented as a framework for correct discernment of material experience.
Vāyu-deva addresses a learned brāhmaṇa, giving a concise doctrinal instruction about the elemental qualities, as part of a broader didactic conversation in the Ashvamedhika Parva.
