Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 7
Sanskrit:
संस्तुत्य मुनयो रामं प्रयुज्यावितथाशिष: ।अभ्यषिञ्चन् महाभागा वृत्रघ्नं विबुधा यथा ॥ ७ ॥
ITRANS:
saṁstutya munayo rāmaṁprayujyāvitathāśiṣaḥabhyaṣiñcan mahā-bhāgāvṛtra-ghnaṁ vibudhā yathā
Translation:
The exalted sages honored Lord Rāma with sincere prayers and awarded Him infallible blessings. Then they performed His ritual bath, just as the demigods had formally bathed Indra when he killed Vṛtra.
