na hi tejasvināṃ śāpāstejaḥsu prabhavanti vai |
balānyatibalaṃ prāpya nabalāni bhavanti vai || 15 ||

"Brahman said, 'Ye foremost of deities, Agni was not there at the time the curse was denounced by the goddess. Even he will beget a son for the destruction of the enemies of the gods. Transcending all the deities and Danavas and Rakshasas and human beings and Gandharvas and Nagas and feathery creatures, the offspring of Agni with his dart, which in his hands will be a weapon incapable of being baffled if once hurled at the foe, will destroy Taraka from whom your fear hath arisen. Verily, all other enemies of yours will also be slain by him. Will is eternal. That Will is known by the name of Kama and is identical with Rudra's seed a portion of which fell into the blazing form of Agni. That energy, which is a mighty substance, and which resembles a second Agni, will be cast by Agni into Ganga for producing a child upon her in order to effect the destruction of the enemies of the gods. Agni did not come within the range of Uma's curse. The eater of sacrificial libations was not present there when the curse was denounced. Let the deity of fire, therefore, be searched out. Let him now be set to this task. Ye sinless ones, I have told you what the means are for the destruction of Taraka. The curses of those that are endued with energy fail to produce any effect upon those that are endued with energy. Forces, when they come into contact with something that is endued with stronger force, become weakened.
