Like a wild animal, the soul is tough, resilient, resourceful, savvy, and self-sufficient: it knows how to survive in hard places. I learned about these qualities during my bouts with depression. In that deadly darkness, the faculties I had always depended on collapsed. My intellect was useless; my emotions were dead; my will was impotent; my ego was shattered. But from time to time, deep in the thickets of my inner wilderness, I could sense the presence of something that knew how to stay alive even when the rest of me wanted to die. That something was my tough and tenacious soul.
