The secret of the transformation lies in the transference of our centre of living to a higher consciousness and in a change of our main power of living. This will be a leap or an ascent even more momentous than that which Nature must at one time have made from the vital mind of the animal to the thinking mind still imperfect in our human intelligence. The central will implicit in life must be no longer the vital will in the life and the body, but the spiritual will of which we have now only rare and dim intimations and glimpses.
