Araṇya-kāṇḍa
Chapter 57: Śrī Rāma Meets Lakṣmaṇa
While Mārīca died, Śrī Rāma heard him cry out in a voice that imitated His own voice. After this He also noticed evil omens. He therefore became apprehensive that Sītā-devī might be in critical danger and rushed towards His āśrama when He met Lakṣmaṇa on the way. He chastised Lakṣmaṇa for having come to Him after leaving Sītā alone in the forest. Śrī Rāmacandra also pointed out that the evil omens indicated that Sītā could have been killed or kidnapped.
