Vaisampayana said, 'After Vasudeva had ceased to speak, the great Yogin, viz. the Island-born Krishna, addressed Yudhisthira, saying,--O son, do thou recite this hymn consisting of the thousand and eight names of Mahadeva, and let Maheswara be gratified with thee. In former days, O son, I was engaged in the practice of severe austerities on the breast of the mountains of Meru from desire of obtaining a son. It is this very hymn that was recited by me. As the reward of this, I obtained the fruition of all my wishes, O son of Pandu. Thou wilt also, by reciting this same hymn, obtain from Sarva the fruition of all thy wishes.
This hymn leads to heaven. It dispels disease and bestows long life.

Then Jamadagni's son, that foremost of all righteous persons, shining like the Sun with blazing splendour in the midst of that conclave of Rishis, said unto the son of Kunti these words;--I was afflicted with the sin, O eldest son of Pandu, of Brahmanicide for having slain my brothers who were all learned Brahmanas. For purifying myself, I sought the protection, O king, of Mahadeva. I hymned the praises of the great Deity by reciting his names. At this, Bhava became gratified with me and gave me a battle-axe and many other celestial weapons. And he said unto me,--Thou shalt be freed from sin and thou shalt be invincible in battle; Death himself shall not succeed in overcoming thee for thou shalt be freed from disease.--Even thus did the illustrious and crested Deity of auspicious form said unto me. Through the grace of that Deity of supreme intelligence I obtained all that He had said.
