शरौघेण hail of shafts, मेघेनेव by cloud, अभिवृष्टः when rained, महाबलः mighty strong, ततः that, रूपम् form, ह्रस्वम् small size, कृत्वा reducing, ध्वजाग्रे top of bow, निपपातह landed.

M N Dutt

Assailed with fearful showers of arrows as with a mass of clouds, that one endowed with eminent strength, decreasing his dimensions, dropped on the top of Ravana's banner.

Summary

When Neela was covered by Ravana's arrows, it was just as clouds cover mountain peaks. Neela reduced his size and landed on top of Ravana's bow.
