Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As their weapons and mantras decreased, the demons began showering mountain peaks, trees and stones upon the demigod soldiers, but the demigods were so powerful and expert that they nullified all these weapons by breaking them to pieces in the sky as before.
