A different viewpoint differing from this theological concept is the concept of Krishna as an avatar of Narayana or Vishnu. It should be however noted that although it is usual to speak of Vishnu as the source of the avatars, this is only one of the names of the God of Vaishnavism, who is also known as Narayana, Vasudeva-Krishna, and just Krishna, and behind each of those names there is a divine figure with attributed supremacy in Vaishnavism.
