ALONE BY THEMSELVES

This is the difference between the earlier avataars and the later. In the Raama-avataar, the course of human conduct and the dharma governing it come linked together. This has been made explicit by Vaalmeeki:

On the occasion of Seeta's ordeal by fire at the end of the battle, Raama says to Brahma who appeared then among others and deprecated the idea of putting Seeta to proof: -

"I regard myself only as Raama, son of Dasaratha, an ordinary human being. Who I am in reality, where I belong, why I took birth, are matters on which you must enlighten me, and I do not know."
