The capacities by which we can gain insights into higher worlds lie dormant within each one of us. Mystics, gnostics, and theosophists have always spoken of a world of soul and spirit that is as real to them as the world we can see with our eyes and touch with our hands. Listening to them, we can say to ourselves at every moment: "I know that I, too, can experience what they talk about, if only I unfold certain forces within me that today still lie dormant there." All we need to know is how to begin to develop these faculties for ourselves.
