But before developing knowledge for these areas, other methods of imagination and concentration must be added to those described. These other methods go in the direction of the will. Just as thought, for ordinary consciousness, is dependent on the brain and nervous system — I cannot go into the details here, but for those who are truly familiar with modern scientific developments, this will be beyond question — so too is the human will, as it unfolds in all that leads a person to action, dependent first of all on the human physical organization. Just as one has to free the life of thought from the bodily organization for supersensible research, so one also has to free the life of will from the bodily organization. But even that strong effort of the will, which one must unfold in imaginative knowledge, leads one to gradually apply the will in a body-free way.
