Those who belong to the esoteric school of the Sufi Movement, are given besides personal guidance, the studies which are entrusted only to those who are fitted to receive them. There are subtleties of ideas, of spiritual, moral, or philosophical ideas, which cannot be given to everyone at first, but they are given gradually to those who are serious enough to walk in the path of truth. But every seeker after truth must remember one thing: that the first step in the path of truth is to become true to oneself.
