Joki has been famous for his farewell poem (composed before his death), saying "Meditation does not always require a quiet place. If you have established your own philosophy, nothing will trouble you as if you would feel fire cool.(安禅必ずしも山水を用いず、心頭滅却すれば火も亦た涼し" (The original text written by Jukukaku TO says "as if fire itself would be cool.(火も自ずから涼し) "
このとき残した「安禅必ずしも山水を用いず、心頭滅却すれば火も亦た涼し」の辞世で知られる（杜荀鶴の原典は「…火も自ずから涼し」）。
