In plain words
You need not grieve over this. In this world happiness and sorrow are both there in equal measure. We must accept them with an even mind.”
Hardship and happiness, the two, live joined together; it is in no one's power to part them; happiness by itself we shall nowhere see; when hardship bears fruit, they call it happiness.
Lakṣmaṇa told her what had happened, and let her know that he too was going to the forest with Sītā and Rāma and would not return for fourteen years. Ūrmilā had a great spirit of sacrifice. She did not grieve that her husband was leaving her and going away. She rejoiced greatly that her husband had been given the chance to serve Sītā and Rāma. She bowed at his feet and bade him farewell with joy.
The presence of God alone is the true treasure
Lakṣmaṇa's mother Sumitrā was a woman of great virtue, true to her name. When Lakṣmaṇa told her that he too was going to the forest to serve Sītā and Rāma, she gladly gave her consent. “My son! I have no sorrow that neither of my two sons has the chance to become king. That day, when a kite came and snatched away my bowl of pāyasa, Kausalyā gave me half of her pāyasa. Kaikeyī too gave half of her pāyasa. You are the one born of Kausalyā's pāyasa. The one born of Kaikeyī's pāyasa is Śatrughna. So you must serve Rāma; Śatrughna must serve Bharata. To be granted such a privilege of service is truly your good fortune,” she said, overjoyed. “Where God is, there the devotee will be. Where the devotee and God are, there victory comes. The presence of God alone is your treasure, my son! So go, by all means, and return,” she said, and blessed Lakṣmaṇa and sent him off. But Kausalyā, grieving: “My son! Are you leaving us in Ayodhyā, with every comfort, and going to the forest, full of every hardship?” she said.
