Besides Hinduism, Lord Krishna is also a part of another religion which is called Jain religion. He's spoken to as one of the triads named Vasudeva. Even in Buddhism, he is a part of the Jattaka tales where he is represented as a Prince who kills his evil uncle Kansa and proves himself legendary by killing all the Kings to rule over Jambuziwa. Hindu scriptures have no record of Radha, though the tales of Radha Krishna is considered one of the greatest love in the world
