But the cessation of the discriminating-mind can not take place until there has been a "turning-about" in the deepest seat of consciousness. The mental habit of looking outward by the discriminating-mind upon an external objective world must be given up, and a new habit of realizing Truth within the intuitive-mind by becoming one with Truth itself must be established. Until this intuitive self-realization of Noble Wisdom is attained, the evolving mind-system will go on. But when an insight into the five Dharmas, the three self-natures, and the twofold egolessness is attained, then the way will be opened for this turning-about to take place. With the ending of pleasure and pain, of conflicting ideas, of the disturbing interests of egoism, a state of tranquillization will be attained in which the truths of emancipation will be fully understood and there will be no further evil out-flowings of the mind-system to interfere with the perfect self-realization of Noble Wisdom.
