उमांशिवं हुताशं च तृतीयायां च पूजयेत् / हविष्यमन्न नैवेद्य देय दमनकं तथा
umāṃśivaṃ hutāśaṃ ca tṛtīyāyāṃ ca pūjayet / haviṣyamanna naivedya deya damanakaṃ tathā
On the third lunar day (Tṛtīyā), one should worship Umā and Śiva, and also Agni. As a food-offering (naivedya), one should present haviṣya-type fare, and likewise offer damanaka, the sacred fragrant herb/leaf.
Lord Vishnu (in instruction to Garuda)
Concept: Proper worship includes correct deities, correct tithi, and correct upacāras (haviṣya food and sacred leaves), harmonizing household ritual with Vedic fire symbolism.
Vedantic Theme: Unity of worship forms: multiple devatā-upāsanā within a dharmic frame; ritual as a means to cultivate sattva and reverence for cosmic order (ṛta/dharma).
Application: On tṛtīyā, perform simple pūjā to Umā-Śiva and honor Agni (lamp/fire); offer a sattvic haviṣya meal and, where traditional, damanaka leaves/flowers as a fragrant upacāra.
Primary Rasa: shanta

This verse prescribes Tṛtīyā as a specific tithi for honoring Umā–Śiva and Agni with defined offerings, showing that merit (puṇya) is linked to correct timing and ritual purity.
It demonstrates the text’s āchāra focus: worship is not generic, but structured by lunar days (tithis) with appropriate deities and prescribed naivedya such as haviṣya and ritual botanicals like damanaka.
On Tṛtīyā, perform a simple, sattvic worship of Śiva with devotion, offer a pure naivedya (haviṣya-style food), and include a traditional leaf/herb offering where available—prioritizing cleanliness, restraint, and sincerity.
