Peace is not something you can force on anything or anyone... . much less upon one's own mind. It's like trying to quiet the ocean by pressing upon the waves. Sanity lies in somehow opening to the chaos, allowing anxiety, moving deeply into the tumult, diving into the waves, where underneath, within, peace simply is.
There is a desire beneath all surface desire. It is this primary desire that you must uncover and fulfill. When in deepest silence, ask yourself: what is my deepest desire? You will inevitably discover one answer, and one alone. Your deepest desire is to unite your will with God's will. Your deepest desire is union with God... Your deepest desire is to be a co-creator in the image of God. No other desire will fulfill your potential. All other desires are symptoms of the fundamental desire for union with God.
