amsumams ca tapas tepe
kalam mahantam nasaknot
tatah kalena samsthitah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued: King Amsuman, like his grandfather, performed austerities for a very long time. Nonetheless, he could not bring the Ganges to this material world, and thereafter, in due course of time, he died.
