The mystic, by the help of exercises, develops and purifies the breath. Therefore to him, after a certain time, all things become clear in the outer and inner world. There are some who see light before them, there are some who notice colors before their view, also there are some who see forms before their sight. When they talk about it to others, who cannot observe the phenomena, they are considered imaginative; people often laugh at them. The Sufi, therefore, does not speak of any such experience to others; he thinks it is not their world and they will not be able to understand unless they also rise to that sphere. There is no motive for speaking about one's experiences to others except pride, and if someone does this out of vanity his next step will be exaggeration.
