For a Sufi, therefore, not only patience to bear all things is necessary, but to see all things from a certain point of view; that can relieve him for that moment from difficulty and pain. Very often it is his outlook which changes a person's whole life. It can turn hell into heaven, it can turn sorrow into joy. When a person looks from a certain point of view every little pin-prick feels like the point of a sword piercing his heart. If he looks at the same thing from a different point of view the heart becomes sting-proof, nothing can touch it. All things which are sent forth at that person as bullets drop down without having touched him.
