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.
