Wise old Jung insists that it is good and salutory - even necessary for growth - to face one's shadow and to confront one's inner demons. No one is exempt. Who is without fears, neuroses, anxieties? There is darkness in all of us. Don't avoid your demons! Go through them. Bring them into the light and face them fairly and squarely. Only then will you be able to handle them.
The mystical life can be described as a journey into the depths of one's being, a journey to the true self and through the true self to God, who is the Center. Down, down I go through alternate layers of light and darkness, meeting all the slimy monsters and frightening demons that inhabit the subliminal world. And if I progress enough, I meet not only my own little monsters. I meet the monsters of the human race. I meet the root causes of war, oppression, torture, hunger, terrorism. I meet hatred, despair, injustice, atheism, darkness. I meet archetypical evil. I meet it in myself.... We are all responsible.
God is present in all these hurts. He is more present in darkness than in light. He is nearer in a time of desolation than in a time of consolation. Stay with the darkness. Go through it. Don't run away. And through all of this you will expand, making you more and more capable of receiving those sublime communications which come from the darkness of God.
