There is a saying of the mystics that spiritual things, the spiritual teachings, can be given from the heart, can be taken into the heart. That is what the sign of the Sufi Movement denotes. It requires a certain preparation to make the heart a receptacle of the Message. By concentration, by contemplation, and by meditation, the heart is purified, enlarged, and made into a receptacle of the Message. Therefore it is that among many thousand mureeds, if you begin to take the real benefit of the Message, although others are benefitted in another way, the full benefit of the Message is received by knowing how to take the Message.
