16.43

「意惡業道至及輕貪等」者，意惡業道，於意惡行不攝惡思。與思為道，故名業道。此思不可還自作道，故除惡思。及輪王時、北洲人等起輕貪等，非麁顯故，不名業道。問：何故不言加行、後起？解云：麁品現前即成根本，故不別言加行、後起。如下當說。

[On the text,] "Mental bad paths of karma [...] and light greed and the like": Mental bad paths of karma do not subsume bad volition under mental bad conduct. Because they serve as the path for volition, they are called paths of karma; this volition cannot in turn serve as its own path, hence bad volition is excluded. Furthermore, the light greed and the like that arise at the time of a wheel-turning king or among people of the northern continent are not coarse and manifest, and thus are not named paths of karma. Question: Why are preparatory and subsequent actions not mentioned? Explanation: When the coarse grade presents itself, it immediately constitutes the fundamental [path of karma], so preparatory and subsequent actions are not separately mentioned. This will be explained below.
