Nikos Kazantzakis said this quote

Every integral man has inside him, in his heart of hearts, a mystic center around which all else revolves. This mystic whirling lends unity to his thoughts and actions; it helps him find or invent the cosmic harmony. For some this center is love, for others kindness or beauty, others the thirst for knowledge or the longing for gold and power. They examine the relative value of all else and subordinate it to this central passion.
