If we would return to God, and find ourselves in God, we must reverse Adam and Eve's journey, we must go back by the way they came. The path lies through the center of our own soul. Adam and Eve withdrew into themselves from God and then passed through themselves and went forth into creation. We must withdraw ourselves from exterior things, and pass through the center of our souls to find God. We must recover possession of our true selves by liberation from anxiety and fear and inordinate desire.
When you set off on the path, the first thing you do is surrender yourself to a greater power, for you will encounter things you will not understand. You will understand things only with your heart, and that can be a little frightening. For a long time, the journey will seem like a Dark Night, but then any search is an act of faith. But God, who is far harder to understand than a Dark Night, appreciates our act of faith and takes our hand and guides us through the Mystery.
