One who lives each day lives a full life. If you lose the spirit of repetition, your practice will become quite difficult. If your practice is good, you may become proud of it. What you do is good, but something more is added to it. Pride is extra.

An old man living in a destitute and barren town buried all of his money at the base of a tree in his back yard. Each night, he would lift the cover on his treasure and delight upon his possession of it. One brightly lit eve, a thief happened upon the old man as he gloated to himself about his great riches. After the miser had gone to sleep, the thief removed the cover and took all of the old man's treasure. The next night the old man, finding his treasure gone, cursed and spat and shook with rage.
