Acceptance of the frog and the frog’s life implies a jump into the inner world, sinking down into inner reality and there we come again to the same thing—that the anima’s intention is to convert rational consciousness to acceptance of the symbolic life
Von Franz argues that the frog-anima’s transformative power is activated only by the hero’s unconditional acceptance of her nature, which is equivalent to surrendering ego-rationality to the symbolic life of the unconscious.
