劇苦（奇逆反蒼頡篇云劇病篤也集訓曰病篤增甚之辭也方言云病之少愈謂之劇古今正字云從刀豦聲也經文作劇俗字也非正體也豦音渠也）。

Severe suffering (劇苦; qi + ni fanqie. The Cangjiepian says: "Ju (劇) means severe illness." The Jixun says: "It is an expression denoting that an illness is critical and heavily worsening." The Fangyan says: "When an illness improves slightly, it is called ju." The Gujin zhengzi says: "It takes the knife radical (刀) with qu (豦) phonetic." The sūtra text writes 劇, which is a vulgar character and not the standard form. Qu is pronounced qu (渠).).
