The illuminatory experience may come to one who is without previous preparation, seeking, effort, or self-discipline. But if it comes so unexpectedly it leaves just as unexpectedly. The visitant is transient. The effects are permanent. If it be asked why it should come to such a person, who neither desired nor strove for it, when others are unable to secure it despite years of seeking, the answer must be that he worked for it in earlier lives. He has forgotten himself for an interval but the illumination recalls him to the quest even though it passes away: hence the permanency of its moral and mystical results.
