What is the symbol of the Shadow Weekend?

The Mandorla (Mandorla PDF)  is an ancient symbol of two overlapping circles: one white (“The Persona”) and the other black (“The Shadow”). Where these two circles overlap is an almond shaped area (mandorla) — golden in color: therein lies the “Gold” of the Shadow Weekend. 

Robert A. Johnson, a Jungian Analyst says of the Mandorla: “Our own healing proceeds from that overlaps of what we call good and evil, light and dark. It is not that the light element alone does the healing; the place where light and dark begin to touch is where miracles arise. This middle place is a mandorla.”
