This verse establishes a sacred correspondence between the subtle channels and India’s most revered rivers. Iḍā, the left lunar channel, is identified with the Ganges, holiest of rivers. Piṅgalā, the right solar channel, is equated with Yamunā, daughter of the sun god Sūrya. This mapping is not decorative: it invites the practitioner to locate the entire sacred geography of India within the body itself.
