In plain words
It is not right for you to leave your aged husband while he is sunk in grief and come to the forest. He is burning in the fire of separation from me. At such a time you must comfort him and cool the burning of his heart with love and with soft, sweet words. That is your duty. Is not her husband alone a wife's refuge?” he said.
Sītā watched closely as Rāma counselled his mother in this way. At once she looked towards Rāma: “My Lord! You teach your mother that her husband alone is a wife's God, and that to serve her husband is a wife's Dharma. But me you tell to stay on in Ayodhyā and look after my mother-in-law and father-in-law. Then is my husband not God to me? Is it not my duty to serve my husband? Dharma is one and the same for all women, is it not? Is there to be one Dharma for your mother and one for me?” she asked. Then Kausalyā to Rāma: “My son! Dharma is the same for everyone. I cannot escape living through my own karma. But Sītā you must not hurt. Grant her prayer and take her with you. She has given up everything and is coming with you to the forest. So do not hurt her feelings. To protect her is your duty,” she said. From this you can understand how great Kausalyā was in character and how large her heart was.
All living beings are embodiments of Rāma!
The Rāmāyaṇa shows how close, how sacred and how exemplary the bond between mother and child and the bond between brothers should be. Today we celebrate Rāma's birthday precisely so that we may call to mind the ideals of the Rāmāyaṇa. “Rāmo vigrahavān dharmaḥ,” it has been said. Rāma is the embodiment of Dharma. Not only that. Describing Rāma's beauty, Vasiṣṭha said, “Puṃsāṃ mohanarūpāya.” “Rāmacandra! You are the embodiment of Saccidānanda. Your form is such as to enchant even men. Your beauty does not belong to the outer body alone. The boundless, unparalleled Prema and compassion within you, these alone have shaped your form to be so attractive,” he extolled.
