Iḍā is a personified ritual power linked with nourishment and purity. Here she is called Vaiśvadevī, meaning aligned with the All-Gods, and is envisioned as standing beside the sacrifice to protect and cleanse.
It asks her to encompass the sacrificer through disciplined observance (vrata) and to cleanse the god-seeking participants at her ritual ‘station,’ keeping the yajña steady and undefiled.
They mark Iḍā as concretely empowered by core sacrificial substances: ghee (clarity, offering, nourishment) and Soma (ritual vitality). The imagery signals that her protection operates from within the yajña itself.
