Therefore，it is said that the perfect man has no self；the spiritual man has no achievement；the true sage has no name.
“Everything has its proper nature.The nature of everything has its proper limitation.The difference among things is just like that between small and great knowledge，short and long life...All believe in their own sphere，and none is intrinsically superior to others.After giving different illustrations，Chuang Tzǔ concluded with the independent man who forgets his own self and its other，and ignores all the differences.All things enjoy themselves in different spheres，but the independent man has neither achievement nor name.Therefore，he who unites the great and the small is one who ignores the distinction of the great and the small.If one insists on the distinction，the p’eng，the cicada，the small officer，and Lieh Tzǔ riding on the wind—all are troublesome things.He who equalizes life and death is one who ignores the distinction of life and death.If one insists on the distinction，Ta-ch’un，the chrysalis，P’eng Tsu，and the morning mushroom，all suffer early death.Therefore，he who makes excursion in the nondistinction of the great and the small has no limitation.He who ignores the distinction of life and death，has no terminal.Those whose happiness is attached within the finite sphere will certainly have limitation.Though they are allowed to make excursion，they are not able to be independent.” —Kuo Hsiang
