In plain words
Only such teachings are true and eternal; they last for ever. Those who read something on the spur of the moment, learn it on the spur of the moment, and preach it without putting it into practice and without experience, are ignorant. In the world, speaking about a devotee is one thing; speaking about God is another. The sacred books such as the Rāmāyaṇa and the Bhāgavata are the very writings of the great sages of that time, who had become worthy of God's grace and had experienced divinity. That itself is true ‘educare’.
During the exile, when they were in the forest for fourteen years, Śrī Rāma himself, as her guru, taught Sītā many things. She kept them safe in her heart and went on putting them into practice. When the exile was over, Sītā, Rāma and Lakṣmaṇa returned to Ayodhyā. Śrī Rāma's coronation took place in great splendour. The days were passing happily.
One day Rāma called Lakṣmaṇa and ordered him to leave Sītā, who was with child, in the forest and come back. Unable to speak against Rāma's command, Lakṣmaṇa left Sītā alone in the forest and returned to Ayodhyā. Vālmīki, who had bathed in the Gaṅgā and was going back to his āśram, happened to see Sītā. He consoled her, gave her courage and took her to his āśram. Sītā spent her days in unbroken thought of Rāma. When nine months were complete, she gave birth to bonny twin children. They named them ‘Lava and Kuśa’. Under the loving training of the great sage Vālmīki, Lava and Kuśa grew into great warriors, sons worthy of Śrī Rāma.
One day, as Lava and Kuśa reached home, they noticed Sītā wiping away her tears. The two ran and fell at their mother's feet. ‘Mother! Why are you shedding tears?’ they asked. ‘It is nothing, dear children! I could not bear the heat of the sun, and tears came to my eyes,’ said Sītā. But Lava and Kuśa did not believe her words.
