"Like Teresa of Avila, Kazantzakis indicates that behind all appearances lies a struggling divine essence (the "Invisible") that is striving to merge with our hearts just as the mystic is striving to merge with God's. Nonetheless God's striving is on a cosmic scale such that there is something trivial involved when we push anthropocentric images too far in our description of God. Behind any religious face like Buddha's or Confucius's or Jesus' lies the awesome reality of the Tao of the Great Spirit or God — the Great Ecstatic. … We must tame some passions to unleash some others in Kazantzakis's religious eroticism. But no human passion is sufficient to put God under our thumbs. Kazantzakis defines "God" in Spain as "the Power that always gives us more than we are able to receive and always asks for more than we are able to give.""
