Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 2
Sanskrit:
स वै बर्हिषि देवेभ्यो भागं प्रत्यक्षमुच्चकै: ।अददद्यस्य पितरो देवा: सप्रश्रयं नृप ॥ २ ॥
ITRANS:
sa vai barhiṣi devebhyobhāgaṁ pratyakṣam uccakaiḥadadad yasya pitarodevāḥ sapraśrayaṁ nṛpa
Translation:
O Mahārāja Parīkṣit, the demigods were related to Viśvarūpa from his father’s side, and therefore he visibly offered clarified butter in the fire while chanting mantras such as indrāya idaṁ svāhā [“this is meant for King Indra”] and idam agnaye [“this is for the demigod of fire”]. He loudly chanted these mantras and offered each of the demigods his proper share.
