The only dragon that needs slaying is ignorance.

There's this wonderful story about Saint Michael slaying the dragon with the dragon, of course, being self-ignorance, that is to say, self being ignorant of it itself being one without a second. Saint Michael represents the constant reminder that we need to realize all the others are all one self and that the only purpose for our illusioned separateness is togetherness; to escape aloneness.
