The way which the superior man pursues, reaches wide and far, and yet is secret.

Common men and women, however ignorant, may intermeddle with the knowledge of it; yet in its utmost reaches, there is that which even the sage does not know. Common men and women, however much below the ordinary standard of character, can carry it into practice; yet in its utmost reaches, there is that which even the sage is not able to carry into practice. Great as heaven and earth are, men still find some things in them with which to be dissatisfied. Thus it is that, were the superior man to speak of his way in all its greatness, nothing in the world would be found able to embrace it, and were he to speak of it in its minuteness, nothing in the world would be found able to split it.
-Confucius
