अध॑ स्म॒ यस्या॒र्चय॑: स॒म्यक्सं॒यन्ति॑ धू॒मिन॑: । यदी॒मह॑ त्रि॒तो दि॒व्युप॒ ध्माते॑व॒ धम॑ति॒ शिशी॑ते ध्मा॒तरी॑ यथा ॥
अध स्म यस्यार्चयः सम्यक्संयन्ति धूमिनः । यदीमह त्रितो दिव्युप ध्मातेव धमति शिशीते ध्मातरी यथा ॥
adha sma yasyārcayaḥ samyak saṃyanti dhūminaḥ | yad īm aha trito divy upa dhmāteva dhamati śiśīte dhmātarī yathā ||

English translation:

“Of whom smoke-emitting, the flames intensely collect; then, when diffused in the three regions, Agni inflates himself in the firmament, like the blower of a bellows, and sharpens (his flames), as (the fire blazes from the blast) of the blower.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

When diffused in the three regions: yadīm aha trito divi upadhamāti = triṣu sthāṇesu vyāptaḥ, spread in the three regions; or, triāi sthānāni atītya, having gone beyond the three regions; ātmānam upa vardhayati, he blows up or enlarges himself; as the fire blazes from the blast of the blower: the text has śiśīte dhmātari, he sharpens as in a blower; i.e., like the fire, which in the proximity of one blowing with a bellows, blazes up, so Agni sharpens his flames,or of himself adds to their intensity
