Krishna is an incarnation of the Hindu god Vishnu. Vishnu maintains a balance between good and evil. Whenever this balance is about to be disrupted he descends to earth choosing the incarnation best suited to restoring balance to the situation. Krishna is the eighth incarnation of Vishnu, but is also worshipped in his own right. Krishna is sometimes shown with Vishnu’s attributes: the wheel or the conch. As Krishna or Rama (another one of his incarnations), Vishnu’s skin is blue.
