Educational Q&A

The verse links sense-perception to elemental cosmology: taste (rasa) is rooted in the water-element and is known through the tongue, with Soma (the Moon principle) supporting the capacity to discern and enjoy taste.

Vāyu-deva is explaining a doctrinal mapping of elements, senses, and deities—describing how taste is perceived and assigning Soma a functional presence in the tongue for the cognition of taste.
