The Angel and the Dark Man vs The Judge
In my drawing the goat represents the personality who has transgressed into the unconscious and encounters the shadow. The ego is "caught between hammer and anvil, both the accuser and the accused” (C.G. Jung, Memories, Dreams, Reflections). Her desire to leave the farm and return to Nature even if it means facing the wolf is motivated by an unconscious yearning towards wholeness. By leaving the farm she loses her innocence and the challenge now is to avoid wanting that innocence back and endure the feelings of guilt and shame during the integration of the shadow.
Symbolically, the white of the goat with the pink moon halo are analogous to the red and white colors of the conscious personality emerging from the swamp. The pink moon refers to Nick Drake’s song Pink Moon (and none of you stand so tall, Pink Moon’s gonna get you all) and could symbolize the red helmet/spirit that came from meeting the shadow. The tree is shaped like a hand with pointed index finger, the hand of justice pointed at the ego and symbol of the guilt surrounding the meeting of the shadow.
The thistle, with its prickliness, is seen in popular belief as a gift of the Devil. Mythically, it doesn't grow in the Garden of Eden but appears as a curse after the Fall (The Book of Symbols, Taschen, p. 166).
The Fall from Eden perhaps then happens when we fail to recognize the opposites and thus create a shadow.
