Nikos Kazantzakis said this quote

Free yourself from one passion to be dominated by another and nobler one. But is not that, too, a form of slavery? To sacrifice oneself to an idea, to a race, to God? Or does it mean that the higher the model the longer the tether of our slavery? Then we can enjoy ourselves and frolic in a more spacious arena and die without having come to the end of the tether. Is that, then, what we call liberty?
