Fixing your own metaphysics: If a person lacks confidence and drive, then you can start by buying groceries and cooking for yourself—this is called “supplementing fire.” If a cold, reserved, reclusive person can, then you can grow more green plants and get more in touch with nature—this is called “supplementing wood.” If someone is physically and mentally exhausted and feels mentally tense, and if conditions allow, you can try growing some vegetables yourself—this is called “supplementing earth.” If someone has a hesitant personality and lacks decisiveness and nerve, you can try cutting your own hair and doing more hands-on crafts—this is called “supplementing metal.” If someone is restless and irritable, and finds it hard to focus, then you can sit quietly and meditate, and then practice some calligraphy—this is called “supplementing water.”
