We don't talk much about humility in AA, almost never use the word. Maybe that is because, as the spiritual adage has it, if you think you are humble, you are not. But I see enough of freedom, serenity, healing, and unselfishness around me to think it must be hiding there somewhere.
We cannot know that we are illuminated by a great light simply by looking up into the sky. But if we lower our heads and look down at our feet, we can clearly see the long, dark shadow that stretches out from us. We know that the darker and blacker that shadow is, the brighter is the light that shines upon us. Thus, we have been told to look at our own dark shadows [within].
