In plain words
So two portions came to Sumitrā. So the part of Rāma that was in Kausalyā's womb came here as Lakṣmaṇa. The part of Bharata that was in Kaikā's womb came here as Śatrughna. That is why Rāma and Lakṣmaṇa came together on one side, and Bharata and Śatrughna on the other. From the time they were born to Sumitrā, this Lakṣmaṇa and Śatrughna did nothing but cry. How many amulets they tied! How many charms they cast! How many kinds of medicine they gave! But their crying did not stop at all. They gave up sleep and food. They kept on crying all the time. Unable to bear this distress, Sumitrā went to Vasiṣṭha. Vasiṣṭha sat in meditation for five minutes and looked. “Mother Sumitrā, you need not grieve. Take this Lakṣmaṇa and lay him in Rāma's cradle. Take this Śatrughna and lay him in Bharata's cradle,” he said. Taking a little room in this cradle of Rāma, Sumitrā laid Lakṣmaṇa beside Him, with Kausalyā's leave. In Bharata's cradle she laid Śatrughna. From the moment they were laid there, no more crying: only laughter and laughter. Eating their food happily, they grew up well content and sturdy. That is, until each reaches his own source, this anguish cannot be escaped. The river is a part of the ocean. Until it reaches the ocean again, this river has neither peace nor rest anywhere. The fish is a part of the water. However many physical comforts you provide, this fish finds no peace at all until it goes back to the water, its own home. The child is a part of the mother. Until it goes to the mother, however many people pick it up, that child does not stop crying. In the same way, the branch is a portion of the tree. If you cut the branch off the tree, it dries up within a few minutes. In the same way, the jīva is a part of God. So however long this jīva lives with joys, comforts, pleasures and enjoyments, unrest keeps following him. When is true Śānti gained? Only when he joins again with God, his own source, does he experience Śānti. So for every jīva, God alone is the source. To reach this source, Rāma took the form of the journey and moved everywhere.
What forbearance among these brothers! What sacrifice! What generosity! On Mount Citrakūṭa, Bharata brought all the people of his kingdom and fell at Śrī Rāma's feet. “Tvameva rājā dharmajña!” he said. “You alone are the embodiment of Dharma. You alone are fit to rule this kingdom. I have no such fitness.” When he pleaded in many ways like this, Rāma in turn said the same thing back. “You are the rightful one for this. You alone must rule it. You alone know this form of Dharma,” He said. While they were pleading with each other like this, the one saying there was none more fit than the other, and the other saying there was none more fit than him, Vasiṣṭha came in. He taught Bharata that God's mind must not be hurt in the least.
