摩訶止觀 7.65

復次，別約出假意者：分別無量藥、病，悉是假名；假名無實，無實故空，是名「空門」。空尚無空相，況有假相？故名「無相門」。空、假無相，亦不願求知病識藥，故名「無願」。此出假智王臣（云云）。

Furthermore, explaining specifically with respect to emerging into the provisional: discerning immeasurable medicines and illnesses are all provisional designations; provisional designations have no reality, and having no reality they are empty—this is termed the 'gate of emptiness'. Emptiness does not even possess the sign of emptiness, how much less could there be a provisional sign? Hence it is termed the 'gate of signlessness'. Both emptiness and the provisional being signless, neither does one aspire or seek to know illnesses and recognize medicines; hence it is termed 'wishless'. These wisdoms of emerging into the provisional are king and minister (and so forth).
