How is the sanctity of marriage bond portrayed throughout the narrative?

The bond of marriage is sacred to the main character Rama and Sita, but marriage is not held on a pedestal in the relationships of the parents or others. The narrative portrays the marriage of Rama and Sita, who both are considered royalty and deeply in love with one another. “To a woman her husband is verily god himself… Even a pious woman who is otherwise righteous, if she does not serve her husband, is deemed to be a sinner (Ayodhya 24-25).” This was spoken from Rama to his mother, Kausalya, explaining the importance of a wife to her husband. Kausalya wishes that Rama would not disperse into the forest for which she will burn to her death without him. Rama wished that his mother stay put and take care of his father like any wife should but she would rather be with the one whom she gave birth too because her husband was occupied with his other wives. On the other hand, Rama had yet to tell Sita, his wife, that he was succumbed to the forest for fourteen years and that he had to leave her behind in respect to his father wishes. Sita insists she follow him to the forest where she says “I should go too; I am your half: and because of this, again I will not be able to live separated from her husband.” She also compares being with her husband as if being in heaven. “Life with the husband is incomparably superior to life in a palace, or an aerial mansion, or a trip to heaven! … Nor will I regard life in the forest as exile or as exile or as suffering. With you it will be more than heaven to me. It will not be the least hardship to me; without you, even heaven is hell (Ayodhya 26-27).” Their love is filled with passion and they both would sacrifice their life for one another. As for other character such as Ravana, who has abducted Sita and wishes to marry her, does not value his marriage seeing that he has multiple wives and has abducted other wives in the past. Even though Rama and Sita only belonged to each other, their society accepted polygamist actions.
