"Then at the command of the lord of wealth, the dead bodies of the Rakshasas were removed from the summit of the mountain. As the intelligent Agastya had fixed this period as the limit of (the duration of) his curse, so being slain in conflict, the Rakshasas were freed from the imprecation. And being honoured by the Rakshasas, the Pandavas for several nights dwelt pleasantly in those habitations."
