And so the evening follows the day, and this goes on till eternity. For a Sufi, therefore, it is not only patience to bear all things that is necessary to relieve him momentarily from difficulty and pain, but also seeing all things from a certain point of view. Very often it is the outlook which changes a person's whole life. It can turn hell into heaven; it can turn sorrows into joy. When a person looks from a certain point of view, every little pinprick feels like the point of a sword piercing his heart, but when he looks at the same thing from a different point of view the heart becomes sting-proof; nothing can touch it; all the things which are thrown at him like stones drop down without having touched him.
