It's Taoist, and it's a short tour in the Book of Health Preservation. It says: think less, read less, desire less, do less, talk less, laugh less, worry less, be happy less, be happy less, be angry less, be good less, be evil less, achieving these twelve is the capital of health preservation. Too much thinking is dangerous, too much thinking is distracting, too much longing is harmful, exhausted, too much talking is arguing, too much laughing is harmful, too much worrying is fear, too happy is flooding, too happy is forgetting your mistakes, too angry is uncertain, too fond of obsession is incurable, too evil is fried without joy, which is the root of death.
