How it relates to vitality and the will
June 2nd 2011
Of the five fingers, the thumb is the one more particularly related to vitality and the will. And so it has often been observed that when people begin to lose either of these qualities they move their thumb less and less. You may not be in the habit of paying attention to your thumb, and yet you should. In order to keep your will in good condition, always awake and active, get used to keeping your thumb out. Never make a fist with your thumb inside. Anyone who does this will soon fall ill, or else their affairs will collapse because of their wavering willpower. The thumb in this position is like a snake hiding its head when it is asleep. Conversely, anyone who keeps their thumb right out, opposite the other fingers, is demonstrating that they are drawing all their forces together into one, thus preventing them from becoming dispersed.
