Rama Beheads Renuka and Receives Boons
Rama, the destroyer of enemy warriors, enters the hermitage last. The great ascetic Jamadagni tells him in great anger: kill your evil mother, without any compassion. Rama grasps his axe and slices off his mother's head. Then Jamadagni's anger is suddenly appeased, and he offers Rama any wishes — which Rama uses to undo everything that was done.
Rama, the destroyer of enemy warriors, entered the hermitage last.
The great ascetic Jamadagni told him in great anger: "O son! Kill your evil mother, without any compassion."
At that, Rama grasped his axe and sliced off his mother's head.
The anger of the great-souled Jamadagni was suddenly appeased. He said in a pleasant voice: "O son! At my words, you have performed a difficult feat. O one learned in dharma! Ask for anything you desire, as many wishes as may be there in your heart."
Thereupon, Rama asked that his mother might live again. That he should not retain any memory of the slaying. That he should not be touched by the sin. That his brothers might return to their natural state. That he might be unrivalled in battle. And that he should have a long life.
The great ascetic Jamadagni granted him everything that he wished for. Aranyaka Parva, Chapter 413
