When a soul has advanced so far on the spiritual road as to be lost to all the natural methods of communing with God; when it seeks Him no longer by meditation, images, impressions, nor by any other created ways, or representations of sense, but only by rising above them all, in the joyful communion with Him by faith and love, then it may be said to have found God of a truth, because it has truly lost itself as to all that is not God, and also as to its own self.
