Enkrateia (Greek ἐγκράτεια, "in power - from ἐν (en, “in”) + κράτος (krátos, “power”). Enkrateia comes from the adjective enkratês (ἐγκρατής from ἐν (en, “in”) which means possession, power over something or someone else + κράτος (krátos, “power”)). It results in the meaning of power over yourself, power over your own passions and instincts, self-control and self-mastery. To Xenophon, enkrateia is not a particular virtue but "the foundation of all virtues".
