Bala Krishna is the eighth son of Devaki and Vasudeva, and is said to have been born to fulfill the prophecy of slaying his tyrannical uncle, Kamsa, the king of Mathura. Legend also has it that Bala Krishna performed many miraculous acts. In the Bhagavata Purana, there is a story about Manigriva and Nalakuvara, which is associated with liberation. In the Bhagavad Gita, one interpretation is that Krishna taught a universal monotheistic religion, and that he is the Svayam Bhagavan.
