In undertaking a spiritual life, what matters is simple: WE MUST MAKE CERTAIN THAT OUR PATH IS CONNECTED WITH OUR HEART... Even the most exalted states and the most exceptional spiritual accomplishments are unimportant if we cannot be happy in the most basic and ordinary ways, if we cannot touch one another and the life we have been given with our hearts... When we ask, "Am I following a path with heart?" we discover that no one can define for us exactly what our path should be. Instead, we must allow the mystery and beauty of this question to resonate within our being. Then somewhere within us an answer will come and understanding will arise. If we are still and listen deeply, even for a moment, we will know if we are following a path with heart.
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.
