Chapter 44: Śrī Rāma Kills Mārīca
Lord Rāma chased the deer with a bow in His hand. When the deer kept changing its course by dint of its magical powers and allured Him, He angrily killed it with an arrow. When Mārīca was about to die, he gave up the body of a deer and assumed his own form. Imitating the voice of Śrī Rāma, he loudly cried out, “Ah, Sītā! Lakṣmaṇa!” Upon hearing Mārīca’s loud cry, Rāmacandra sorrowfully considered that Sītā-devī and Lakṣmaṇa could become distressed and turned back to return to His āśrama.
