The earth is at the same time mother, she is mother of all that is natural, mother of all that is human. She is the mother of all, for contained in her are the seeds of all. The earth of humankind contains all moisture, all verdancy, all germinating power. It is in so many ways fruitful. All creation comes from it. Yet it forms not only the basic raw materials for humankind, but also the substance of Incarnation.
And how does one go chasing after a glimpse of the uncreated Light? The Hesychasts, high on Mount Athos, bowed their heads upon their breasts, took a deep breath, and plunged in. What they plunged into was prayer. It began with a tack with which to fix the attention. It became breath itself, an inlet for the universe to invade one's body until the entire cosmos, drawn in, heaved out, was transformed into prayer. The body's posture was important. The breathing was to be carefully controlled so as to keep time with the words. Eventually the prayer, breathed in, united with their very blood and heartbeat; breathed out, it blessed the world. And some monks claimed after a while to have indeed seen the Light of the Transfiguration, uncreated energy beheld by bodily eyes.
