For Mr. Hofmann, life may be lived at two levels: the life of man within himself, in ""inner space"" as he calls it, and the life of man outside of himself, in ""outer space."" Happiness, and the nature of man, require a balance between the two, the attainment of which constitutes a ""breakthrough to life"" as it should be lived. The present work is a consideration of the problems and rewards of that breakthrough and, at the same time, a do-it-yourself guide to the radical reversal of one's world view which must precede that breakthrough. If the author's style and purpose are reminiscent of the efforts of Norman Vincent Peale, his concepts and ideals are those of Dom Chautard: the establishment and maintenance of an equilibrium in the modern Christian between activism and contemplation, between engagement and withdrawal. Although the whole thing is as cautious as a non-denominational sermon, its principles are sound, fashionably secularized, and clearly examined, and the book may well have a certain vogue in a relatively sophisticated ""inspirational"" market.
