大般涅槃經義記 6.237

6.237

第三段中，文別有二：一明王病重餘藥不療、二「時有大臣名月稱」下彰王病重餘醫不治。前中，初先母為撫瘡，後王對之明其非治。此亦即明世王有解，「瘡從心生，非四大起」是識病也。「眾生能治無有是處」是知治也。

In the third section, the text is divided into two: first, explaining that the king's illness was grave and other medicines could not treat it; second, from "At that time there was a minister named Candrayasas..." downwards, showing that the king's illness was grave and other physicians could not treat it. In the first part, his mother first caresses the sores, and afterwards the king responds to her, explaining that they cannot be treated [by ordinary means]. This also immediately shows that the king of the world had understanding: "The sores arise from the mind, not from the four great elements"—this is recognizing the illness; "There is no possibility that sentient beings could treat it"—this is knowing how it can be treated.
