Then remember my friends, that if you studied Sufism for twenty years, all the problems of metaphysics and philosophy, and if that spirit of brotherhood were not developed in you, you must be sure that progress has not been made. Or if you meditated for thirty years in a solitude, and if you communicated with God, and yet if the spirit of brotherhood is not developed in you, no progress is made. A person who is loved by everybody in the world, and yet if he has not loved anybody, he has done nothing. A person who has possessed the wealth of the whole world, but if he has given nothing, he has not earned. A person honored by everyone in the world, but if he has not respected, he has not lived.
