“Life, death, preservation, loss, failure, success, poverty, riches, worthiness, unworthiness, slander, fame, hunger, thirst, cold, heat - these are the alternations of the world, the workings of fate. Day and night they change place before us, and wisdom cannot spy out their source. Therefore, they should not be enough to destroy your harmony; they should not be allowed to enter the storehouse of the spirit. If you can harmonize and delight in them, master them and never be at a loss for joy; if you can do this day and night without break and make it be spring with everything, mingling with all and creating the moment within your own mind - this is what I call being whole in power.”
