涎涕（上夕延反下體計反口液也經文從夷作洟誤用也字書雖有替音本是夷字易萃卦曰齎恣涕洟是其證也）。

Saliva and nasal mucus (涎涕: the first character has the fanqie 夕延, the second 體計; oral fluid. In the sūtra text it is written with 夷 as 洟, which is an erroneous usage; although dictionaries have the reading [tì] for it, it was originally the character 夷. The Cui hexagram of the Yijing says: "Lamenting with sighs and tears (涕洟)"—this is the proof).
