The mind becomes silent, still, or vanishes.

There are stages along the mystic way--stages which have been interpreted differently by various writers, but which fall into several distinct levels of personal growth. The intuitional step is first. This can best be described as an inner prompting, perhaps a sudden moment of insight, when the individual sense that there is more to life than his ordinary living currently reveals. This awakening can come either in a core-religious experience (also called a conversion experience, a moment of illumination, or a peak-experience during which the individual's mind becomes silent, still or "vanishes") or as an ongoing, increasing "knowing" that the Absolute reality is the one (and only) true and worthwhile life.
