The spiritual function of fierce terrain (in the apophatic tradition) 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.
Another will is greater, wiser and more intelligent than my own. So I wait. Waiting means that there is Another whom I trust and from whom I receive. My will, important and essential as it is, finds a Will that is more important, more essential. .. In prayer we are aware that God is in action and that when the circumstances are ready, when others are in the right place and when my heart is prepared, I will be called into action. Waiting in prayer is a disciplined refusal to act before God acts. Waiting is our participation in the process that results in the "time fulfilled".
