And they would chase even the gods, the Gandharvas, and the Rakshasas and all the born beings, being themselves valiant and addicted to fight.

In a not very long space of time, there will come about, O gods ! a great and exceedingly terrible destruction of Sagara's sons, caused by the deed perpetrated by them . -- Thus addressed those same gods, and men, O lord of the sons of Manu ! bade adieu to the grandfather, and went back to whence they had come.
