God is perfect being. Everything else that exists is only half, only a part, is becoming, is mixed, is made up of potentialities. But God is not mixed. He is one, he has no potentialities but is the total, the complete reality. Whereas we are transitory, we are becoming, we are potentials; there is no perfection for us, no complete being. But wherever we go, from potential to deed, from possibility to realization, we participate in true being, become by a degree more similar to the perfect and divine. That is what it means to realize oneself.
