Nothing makes time pass more quickly or more shortens a journey than a thought which absorbs in itself all the faculties of the organization of him who thinks. External existence then resembles a sleep of which this thought is the dream. By its influence, time has no longer measure, space has no longer distance. We depart from one place, and arrive at another, that is all. Of the interval passed, nothing remains in the memory but a vague mist in which a thousand confused images of trees, mountains, and landscapes are lost.
