2.69

「亦可」下，約病從外入。如久視久聽，乃至飲食皆成病故。具論者，外入乃是病緣，入傷五藏。五藏既病，外應五根，五根亦病也。「夜叉」，新云藥又，此翻勇健，能飛騰空中。舊翻捷疾鬼。「致令國人病惱」者，即是鬼為病緣。由鬼氣外陵五根、入傷五藏，五藏成病，還應五根。

From "It may also" below, it treats illness entering from outside. For instance, prolonged looking or prolonged listening, and even food and drink, all result in illness. Fully discussed: external entry is merely the condition for the illness, entering and injuring the five viscera. Once the five viscera are diseased, they externally correspond to the five sense faculties, and the five faculties also become diseased. "Yakṣa": recently translated as yaoxiu, translated here as "brave and robust," able to fly and soar in the air. Formerly translated as "swift spirit." "Causing the people of the state to suffer from illness and affliction": this is the spirits serving as the condition for the illness. Because the vapor of the spirits externally assails the five sense faculties and enters to injure the five viscera, the five viscera become diseased, which in turn corresponds to the five faculties.
