Canto 3 -
Araṇya-kāṇḍa
Chapter 49: Rāvaṇa Kidnaps Sītā

Rāvaṇa gave up his appearance of a sannyāsī and revealed his real form. He then caught Sītā-devī by her hair, put her on his chariot and departed for Laṅkā. Sītā humbly requested the mountains, trees, Godāvarī and so on to inform Lord Rāma about these incidents. Standing on the chariot, she cried out for help in various ways when she noticed Jaṭāyu on the way. She loudly requested him to inform Rāma of the events that had taken place.
