अन्वयः

अतिवृत्तः acted beyond his limit, खरः Khara, रणे: in war, रामेण: by Rama, हतःयदि has been killed also, प्राणिना: by living beings, यथाबलम् their own strength, प्राणाः life, अवश्यम् certainly, रक्षितव्याः will have to protect.

M N Dutt

If Khara, who had trespassed into regions not his own, has buen slain in battle by Rāma, surely a creature should to the best of his might preserve his life.

Summary

"(It is true) Khara was killed by Rama in war as he acted beyond his limit. Certainly, living beings will have to protect their life with their own strength."
