Those who because of their materialistic view cannot believe in the God ideal lose a great deal in their lives. That ideal which is the highest and best ideal, the only ideal worth loving, worth worshiping, worth longing for, worth and through the darkness of night, is God. He who has God in his life has all he needs; he who has not God, though he may have all things of this mortal world, is lonely. He is in the wilderness even if he be in the midst of the crowd. The journey of the Sufi, therefore, is to God. It is divine knowledge which he seeks; it is the realization of God-consciousness which is his goal.
