Description
If only sensory phenomena are within the reach of scientific research, the doors are closed to those worlds from which the human being originates and where the creative forces of the world are found. Rudolf Steiner challenges us to develop organs of perception needed to go beyond these limits of perception, so that we can witness the spirit that is active in all natural phenomena.
