garhayanneva rāmastu tvaritastaṃ samāsadat |
api jīvati vaidehī neti paśyāmi lakṣmaṇa || 13 ||

"And while Sita was being carried away, the intelligent Rama, having slain the great deer, retraced his steps and saw his brother Lakshmana (on the way). And beholding his brother, Rama reproved him, saying, 'How couldst thou come hither, leaving the princess of Videha in a forest that is haunted by the Rakshasa?' And reflecting on his own enticement to a great distance by that Rakshasa in the guise of a deer and on the arrival of his brother (leaving Sita alone in the asylum), Rama was filled with agony. And quickly advancing towards Lakshmana while reproving him still, Rama asked him, 'O Lakshmana, is the princess of Videha still alive? I fear she is no more!' Then Lakshmana told him everything about what Sita had said, especially that unbecoming language of hers subsequently. With a burning heart Rama then ran towards the asylum. And on the way he beheld a vulture huge as a mountain, lying in agonies of death. And suspecting him to be a Rakshasa, the descendant of the Kakutstha race, along with Lakshmana rushed towards him, drawing with great force his bow to a circle.
