At some point his mind slips from its accustomed anchorage; an impersonal consciousness that is not his own and knows nothing of himself takes over, and all memories of experience in the world lapse as if they never were. He is isolated from everything and everyone. Only a knowingness remains. At first the loss of personality induces fear as he feels its onset but if he holds his ground and lies still, unresisting, quiet, trusting the beneficence of the process, the fear of it ebbs and vanishes. Then a calm, before unknown and now unutterable, replaces it. Such an experience will be remembered long after all others are forgotten.
