Śrīmad-Bhāgavatam · Text 11.4.21
Who is speaking and story frame
नि:क्षत्रियामकृत गां च त्रि:सप्तकृत्वो
रामस्तु हैहयकुलाप्ययभार्गवाग्नि: ।
सोऽब्धिं बबन्ध दशवक्त्रमहन् सलङ्कं
सीतापतिर्जयति लोकमलघ्नकीर्ति: ॥ २१ ॥
niḥkṣatriyām akṛta gāṁ ca triḥ-sapta-kṛtvo
rāmas tu haihaya-kulāpyaya-bhārgavāgniḥ
so ’bdhiṁ babandha daśa-vaktram ahan sa-laṅkaṁ
sītā-patir jayati loka-mala-ghna-kīṛtiḥ
Lord Paraśurāma appeared in the family of Bhṛgu as a fire that burned to ashes the dynasty of Haihaya. Thus Lord Paraśurāma rid the earth of all kṣatriyas twenty-one times. The same Lord appeared as Rāmacandra, the husband of Sītādevī, and thus He killed the ten-headed Rāvaṇa, along with all the soldiers of Laṅkā. May that Śrī Rāma, whose glories destroy the contamination of the world, be always victorious.
