Excerpt from The Inner Chamber of the Science of Mentalphysics We should do all that we can to become convinced of the possibility of living to a great age. Every bit of evidence that comes our way should be carefully considered. To know how to live is, as we have found out, a profound and subtle science, and it is obvious that no other subject of equal importance as longevity can be presented for our consideration. In our consideration of the question of longevity, I as your Teacher must assume that you DO feel the possibility OF living AS long AS you desire TO live.
