The silence of meditation is not the silence of a graveyard; it is the silence of a garden growing. There is no deadness in a garden, but in that all-pervading silence an intense activity is going on in the ground which will later take form as buds, blossoms and fruit. So, too, in meditation there is not a blankness, but a rhythmic activity of the Spirit. As the mind exhausts itself the Spirit comes through, and we are in the realm of heaven. True, we are still on earth, our feet are solidly on the ground -- the holy ground of spiritual awareness.
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.
