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.
The act of inner attention seems to create a medieval walled garden. It is hedged about with silence and stillness, but silence and stillness are not the heart of it. At the center is a fountain and we see that everything has arranged itself around the water playing in the sunlight: here is the source of the timelessness that is everywhere apparent. The more deeply we enter, the more the fountain soars above; awe and wonder claim us.
It asks that we learn how to live, to make a particular path and fullness out of the spirit's eternity and silence.
