The Exposition of the Nityā-paṭala
कृत्वा योनिं कुंडमध्ये तत्राग्नौ विधिवद्ध्रुनेत् । तिलसर्षपगोधूमशालिधान्ययवैर्हुनेत् ॥ १५१ ॥

Having fashioned the yoni-shaped (womb-like) form in the middle of the fire-pit, one should, according to proper rule, kindle the fire there and then perform oblations with sesame, mustard, wheat, fine rice, grains, and barley.
Sanatkumara (in instruction to Narada, within the Vedanga/ritual-technical discourse)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It emphasizes disciplined Vaidika action: shaping the altar/fire-space correctly and offering pure agrarian substances into Agni, aligning the performer with ṛta (sacred order) through precise ritual conduct.
Though primarily ritual-technical, it supports bhakti by teaching that devotion is expressed through careful, rule-based worship—offering sanctified substances into Agni as an act of reverence and surrender.
Kalpa (ritual procedure) is foregrounded: correct construction/placement in the kuṇḍa, proper kindling, and the specified homa-dravyas (sesame, mustard, wheat, rice, grains, barley) for oblations.
