Jung presents the image of the two thieves who were crucified with Jesus as symbols of the two sides of the shadow: one thief reviled Jesus while the other commiserated with him and asked for transformation. These are the opposing sides of our own souls. We fight the entry of the light into our lives and yet yearn for it. Wonderfully, both have a place in the uncovering of inner wholeness. The promise of paradise was instantaneous for the thief who welcomed the light. At the same time, it still remained available for the thief who turned away from it, if he would become willing to enter the purgatorial fires where his own interior darkness could be faced and integrated.
