In plain words
Vasiṣṭha tried to persuade Rāma. “Rāma! For generations our kingdom has stayed under the rule of one alone, never divided. Now you are saying the kingdom must be divided. That is not for the good,” he said. “There is no need to divide it. Each one can rule a region,” said Rāma. But Daśaratha did not agree.
Rāma gave the highest importance to equality and to social justice. All must live as equals; there must be no high and low at all; no room must be given to differences. This was Rāma's ideal. But Daśaratha, because of his old age, was in no state to understand the words Rāma spoke. So Rāma said, “Bharata and Śatrughna must come too.” For them to come would take fifteen days at the least. So He thought that in the meantime the matter could be thought through as it should be. For the time being, the coronation was halted. Rāma's power and ability, His skill and resourcefulness, were most remarkable, most wonderful. That all should be equal is the chief message of the culture of Bhārata. “Sarve janāḥ sukhino bhavantu”, “Lokās samastāḥ sukhino bhavantu.” All must be happy. It was such an ancient culture that Rāma kept to. Today many people read the Rāmāyaṇa; they get hold of books as big as great pillows and keep them; they commit the ślokas to memory. But they do not grasp even a little of their essence.
Kausalyā was a woman of great virtue. Since she was the chief queen, everyone took her command upon their heads. And as for Kaikeyī, Daśaratha's third wife, nothing at all stood in the way of her command either. Even Daśaratha, if she said sit, had to sit; if she said rise, had to rise. In this way she kept Daśaratha in her hand and went on staging her play. But there was no one who paid any heed to Sumitrā. Because Kaikeyī asked that Rāma should live in the forest for fourteen years, the coronation did not take place. Before setting out for the forest, Rāma went to bow to His mother Kausalyā.
