The Kabbalah teaches, Three rulers rule man, the head, the heart, the liver.

The head: do you allow your mind to influence your behavior?

The heart: is your behavior influenced by what feels, tastes, experiences, good/pleasurable; and trying to stay away from fear, fright, pain and discomfort?

The liver: Are you motivated only by being right?

Getting your head to rule, is the objective of the game called life.
