Araṇya-kāṇḍa
Chapter 60: Rāma Searches for Sītā
By seeing the evil omens, Rāma feared that Sītā might be in danger. He then quickly entered His leaf-cottage with Lakṣmaṇa. He didn’t find her even after He searched for her in the places where she used to sport. In distress, He then asked the trees, deer and so on whether they had seen Sītā-devī. When He didn’t find Sītā anywhere, He thought of various possibilities—she might have been eaten up by the rākṣasas and so on. He then repeatedly lamented in various ways and ran through the forest in search of her.
