The reality and importance of this faculty are considered in the first three chapters. In the fourth and fifth is described the preliminary training of attention necessary for its use, in the sixth, the general self-discipline and attitude toward life which it involves. The seventh, eighth, and ninth chapters treat in an elementary way of the three great forms of contemplation, and in the tenth, the practical value of the life in which they have been actualised is examined. Those kind enough to attempt the perusal of the book are begged to read the first sections with some attention before passing to the latter part.
