We are all a combination of what we are born with as well as what we are raised to be. Our natural disposition is known as varna while the cultural indoctrination is jati. Krishna is by varna a nobleman but by jati a cowherd. Though nobleman, he can never be king. Though cowherd, he can always lead.
