大般涅槃經義記 3.153

3.153

第二愚人不別喻中，「諸人欲買然不識」者始時不別，「至賣藥」下中間不別，初問、次答。「是人」下與，與其邪法名「以雜藥」，嘆非為是，故言「此是雪山甘藥」。「時買」下取闇昧之心不達邪正，故言「肉眼不能善別」。聞說聽受名「買持去」。「復作言」下終時不別，取非為是，故言「我得雪山甘藥」。

In the second simile of foolish people not distinguishing, "the people wished to buy but did not recognize it" means not distinguishing at the beginning; from "went to the seller of medicine" onward means not distinguishing in the middle, first asking and then answering. From "this person" onward, giving them the false dharma is called "giving mixed medicines"; praising the wrong as right is therefore said as "this is the sweet medicine of the Snow Mountains." From "at that time buying" onward, taking it with a darkened mind that fails to comprehend the false and the true is therefore said as "the flesh eye cannot properly distinguish." Hearing the exposition and receiving it is called "bought it and carried it away." From "further spoke words" onward means not distinguishing at the end; taking the wrong as right, they thus say "I have obtained the sweet medicine of the Snow Mountains."
