In plain words
“Shall I go free of this prison? Shall I ever again reach Rāma's presence? O Lakṣmaṇa, my dear brother-in-law! I spoke harsh words to you, good soul! Stung so by the words of my mouth, did you leave me, my son? Forgive me”
So she repented deeply within herself. But what use was it? What should not have happened had already happened.
Learning that Rāvaṇa had carried Sītā off and taken her to Laṅkā, Rāma and Lakṣmaṇa laid siege to Laṅkā with the army of vānaras. In the battle with Indrajit, Lakṣmaṇa fell senseless. To bring the herb that would end his swoon, Hanumān went to the Sañjīvinī mountain. But, unable to tell the herbs apart, he uprooted the mountain itself, held it in his hand and set out. As he went along the path of the sky, the people of Ayodhyā: ‘Who is this? He's carrying off a hill!’ they said in wonder. Seeing Hanumān and taking him for some demon, Bharata shot an arrow. Then Hanumān came down and told all that had happened. “In the battle Lakṣmaṇa has fallen senseless. Bearing Rāma's command on my head, I went to the Sañjīvinī mountain. But since I did not know which herb it was, I am carrying off the mountain itself,” he explained.
