At this moment Krishńa, accompanied by Nárada, arrived; and the latter said to the delighted Rukminí, "This is thine own son, who has come hither after killing Sambara, by whom, when an infant, he was stolen from the lying-in chamber. This is the virtuous Máyávatí, his wife, and not the wife of Sambara. Hear the reason. When Manmatha, the deity of love, had perished, the goddess of beauty, desirous to secure his revival, assumed a delusive form, and by her charms fascinated the demon Sambara, and exhibited herself to him in various illusory enjoyments. This thy son is the descended Káma; and this is the goddess Ratí, his wife. There is no occasion for any uncertainty: this is thy daughter-in-law." Then Rukminí was glad, and Keśava also; the whole city resounded with exclamations of joy, and all the people of Dwáraká were surprised at Rukminí's recovering a son who had so long been lost.
