years later, king rituparna revealed to bahuka the supreme skill of controlling the dice in exchange for horsemanship lessons. this skill awakened nala from kali's control and allowed him (with the help of damayanti's curse and karkotaka's venom) to exorcise the demon; vomiting him in the form of poison from his mouth. nala forced the kali's trembling spirit into a vibhitaka tree. he then counted the fruits of the tree and left in search of his wife and later regained his true form. kali returned to his abode as well.
