कपिः monkey, महालतानाम् of huge creepers, दामानि hanging, तरसा with tremendous speed, मारुतः wind, प्रावृषि in the rainy season, विन्ध्यस्य of Vindhya, मेघजालानि clusters of clouds, यथा like wise, व्यथमत् shook.

Hanuman shook with tremendous speed the huge clusters of creepers hanging there just like stormy wind in rainy season scatters masses of clouds on the Vindhya mountain.
