There comes a pause, for human strength will not endure to dance without cessation; and everyone must reach the point at length of absolute prostration.
~ William Wordsworth in "The Prelude" from THE POETICAL WORKS OF WILLIAM WORDSWORTH
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.
