肇論新疏 2.420

2.420

是以聖人空洞其懷，無識無知，然居動用之域，而止無為之境；處有名之內，而宅（居）絕言之鄉。寂寥虛曠，莫可以形名得。若斯而已矣！

Therefore, the sage completely empties his bosom, without consciousness and without knowledge; yet he abides in the realm of movement and function while residing in the state of non-action; he dwells within the domain of the named, while lodging (dwelling) in the homeland that cuts off speech. Silent, empty, and vast, he cannot be attained through shape or name. It is just like this!
