इन्द्रेण by Indra, अश्मवृष्टिभिः by raining hailstones, आहतम् destroyed, उत्तमं सस्यमिव like the crop ready for harvest, शरवृष्टिभिः rain of arrows, हन्यमानम् killed, तत् सैन्यम् that army, पश्यामि witnessed.
Just as Indra destroys the crop ready for harvest by raining hailstones, I have seen Rama killing the army with a shower of arrows.
