To find the truth you must have feeling, a passion for finding out, great energy. Then you will find that thought breeds fear; thinking about the past or the future-the future being the next minute or the next day or ten years hence- thinking about it makes it an event. And thinking about an event which was pleasurable yesterday, sustains or gives continuity to that pleasure, whether that pleasure be sexual, sensory, intellectual or psychological; thinking about it, building an image as most people do, gives to that event in the past a continuity through thought and breeds more pleasure.
