But man finds the reason for all affliction in the life outside him. The Sufi finds it in that one sin, that of having claimed to be "I." With this claim came all the trouble, it continued, and it will always continue. This sin has such a hold upon the soul that it is just like the eclipse of the sun, when its light is covered and cannot shine. In everyday life one may sometimes find this claim and the spirit of "I" helpful, and so the practical man looks upon a person who has less of this element as weak; he thinks that he is unpractical. If this person seems more simple he calls him dreamy, he will say that he is floating in the air. But after all, how long does this practical sense last, and to what end does it lead? The end of the one who was practical and the end of the unpractical one are the same.
