The Determination of Śiva as the Meaning of Praṇava
अथ महाव्रतमिति अग्निर्वै देवा नामतः । तथैतस्य समाम्नायमिषेत्वोर्ज्जे त्वा वेति तत्
atha mahāvratamiti agnirvai devā nāmataḥ | tathaitasya samāmnāyamiṣetvorjje tvā veti tat
Next, the rite called “Mahāvrata” is, in truth, Agni—known among the gods by that very name. Likewise, its traditional recitation is: “iṣe tvā, ūrje tvā”—‘for nourishment I invoke you; for strength I invoke you.’

It identifies Mahāvrata as inseparable from Agni and mantra—showing that a “great vow” is not mere austerity, but a consecrated act sustained by sacred fire and right recitation, supporting inner purification in the Shaiva path.
In Saguna Shiva worship, offerings to the Linga are commonly accompanied by Agni-related rites and Vedic utterances; this verse frames the vow as a mantra-guided, fire-sanctified observance that supports external worship and internal devotion toward Shiva.
Perform the Mahāvrata with disciplined observance and recite the received formula “iṣe tvā, ūrje tvā,” cultivating the intent of nourishment and strength—qualities to be offered back into Shiva-oriented sādhanā.
