淳淨（上常倫反經作淳俗字也考聲渟漬也鄭注儀禮云沃也廣雅漬也茲四反說文𥂖音淥從水[古/(畢-田+目)]聲[古/(畢-田+目)]音純也）。

淳淨 (The first character has the fanqie: 常倫. In the sūtra it is written as 淳, which is a vulgar character. The Kaosheng says: "To steep or soak." Zheng's commentary on the Yili says: "To pour water upon." The Guangya says: "To soak"; the sound is fanqie: 茲四. The Shuowen writes it as 𥂖, pronounced lu (淥), taking the water radical with the phonetic [古/(畢-田+目)]; [古/(畢-田+目)] has the sound of chun (純)).
