The most practical book Hall ever wrote. Twelve “realizations” laid out as a working program of inner discipline: theory of disciplines, inward perception, methods of development, placidity, concentration, philosophical attention, retrospection, extension of consciousness, the material and metaphysical personality, approaching spirituality, illumination, and the suspension of the objective mind. Written for students who wanted a manual rather than another study of symbols.
Manly P. Hall
