To move toward the desert where interior prayer and interior transformation can take place means a willingness to go into the desert, to learn to shut the door, and to move into the necessary solitude which prayer and the deeper levels of worship require.
If I set my heart upon another person, then I cannot live without that person. My heart becomes divided. If I give my heart to my life, on the other hand, if I give my heart to the journey with God, then my heart can be whole in a relationship with another. I can be heart and soul in the relationship because I am heart and soul in the journey of my life.
