“The universe is the general name of all things.The universe has all things for its contents；and the norm of all things must be the natural.What is spontaneously so，not made to be so，is the natural.The p’eng can fly in the high place，the quail in the low.The Ta-ch’un can live for a long time，the mushroom a short one.All these capacities are natural，not made or learned.They are not made to be so，but are naturally so，thus they are normal.Therefore，to chariot on the normality of the universe is to follow the nature of things.To ride upon the transformation of the six elements is to make excursion in the road of change and evolution.If one is going on like this，where can one reach the end？If one will chariot on whatever one meets，what will one have to depend upon？This is the happiness and freedom of the perfect man who unites his own self with its other.If one has to depend upon something，one cannot be happy，unless one gets hold of the thing which one depends upon.Although Lieh Tzǔ could pursue his way in such a fine manner，he still had to depend upon the wind，and the p’eng was even more dependent.Only he who ignores the distinction between things and follows the great evolution can be really independent and always free.” —Kuo Hsiang
