SB 7.10.37
sayanau yudhi nirbhinna-
hrdayau rama-sayakaih
tac-cittau jahatur deham
yatha praktana-janmani
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Pierced by the arrows of Lord Ramacandra, both Kumbhakarna and Ravana lay on the ground and left their bodies, fully absorbed in thought of the Lord, just as they had in their previous births as Hiranyaksa and Hiranyakasipu.
