These books resemble the various sides of a crystal, they reflect always the same and contain always all the light but in a different refraction.
All this is presented in such an ultimate simplicity and clarity, there is such an immediately noticable certainty to it, that one would like to wish as many people as possible this guidance. Here the road is opened up to an inner assurance of life and an affirmation of self that knows neither fear for death or life.
