Recitation
9.21 They, having enjoyed the vast heaven, enter the world of mortals when their merit is exhausted; thus abiding by the injunctions of the ï1threeï1 (Vedas) and desiring (objects of) desires, they attain to the state of going and returning.
When they have thus enjoyed vast heavenly sense pleasure and the results of their pious activities are exhausted, they return to this mortal planet again. Thus those who seek sense enjoyment by adhering to the principles of the three Vedas achieve only repeated birth and death.
