" There are many things in the life of a Sufi, but the greatest is to have a tendency to friendship; this is expressed in the form of tolerance and forgiveness, in the form of service and trust. In whatever form he may express it, this is the central theme: the constant desire to prove one’s love for humanity, to be the friend of all. "
