而子復云未聞行其道者。何蔽也哉（蔽障也。自堯舜至漢唐宋以來聖君賢臣高士明儒行此道者。略舉以曉之。子何不聞而自障蔽也）。

Yet you say again that you have not heard of anyone practicing its Way—how obstructed you are! (Bi means obstructed. From Yao and Shun down through the Han, Tang, and Song, sage rulers, worthy ministers, lofty scholars, and brilliant Confucians who practiced this Way are briefly cited to illuminate this. Why have you not heard and instead obstructed yourself?)
