Confused about which is Ram's ring, Hanuman borrows Lord Brahma's kamandal and carries all the rings in the river of Brahma Lok to Ram. Ram informs Hanuman that all of these rings belong to him and that he had gifted each one of them to Brahma Dev during each of his incarnations on earth. Ram also informs Hanuman that he has been earmarked as the one who will replace Brahma Dev in his role at the end of this age and blesses him with immortality.
