Sundara-kāṇḍa - Part 3 - Hanūmān receives Cūḍāmaṇi from Sītā
Hanūmān, who was hiding behind the branches of the tree, had thus seen and heard everything that had taken place there. He thought, ‘I have found Sītā, but I must not go back without reassuring her. If I don’t do so, she will not survive the night. I must also take her message to Rāma. Let me wait until the rākṣasīs slacken their vigilance. I probably must speak to her employing Saṃskṛta – the cultured language familiar to the humans. But then, she might take me for Rāvaṇa if I speak to her in Saṃskṛta and get frightened.
