The spiritual function of fierce terrain...is to bring us to the end of ourselves, to the abandonment of language and the relinquishment of ego. A vast expanse of jagged stone, desert sand, and towering thunderheads has a way of challenging all the mental constructs in which we are tempted to take comfort and pride, thinking we have captured the divine. The things that ignore us save us in the end.
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.
