If you drive about twenty minutes southwest at sunrise from the Redemptorist Renewal Center monastery in Tucson, Arizona, you’ll find yourself in the barren, beautiful heart of Saguaro National Park. On a June morning like the one I experienced, the dry desert heat will not have yet begun its ascendant day-reign. A coolness mixes with the warm expanse. The group I traveled with broke off from each other, pursuing intentional solitude. Our morning practice: an hour of prayerful walking in the desert, accompanied only by the sturdy presence of saguaro cacti.
