大乘義章 5.17

5.17

第四門中，三門相對辨其優劣。煩惱有三，謂上、中、下。三道煩惱唯在上品，不通中下。故《雜心》云「於中增上說為業道。」又《成實》云「暢思煩惱，必是增上，故說邪見。」若論三根，通取中上，不通下品，微下煩惱不發業故。三毒則寬，三品俱攝。三根等義，略辨如是。

In the fourth section, the three categories are correlated to distinguish their superiority and inferiority. Afflictions are of three types: upper, middle, and lower. The afflictions of the three pathways exist only in the upper grade and do not extend to the middle and lower. Hence the Saṃyuktābhidharmahṛdaya states: "Among them, the predominant ones are spoken of as karmic pathways." Furthermore, the Tattvasiddhi states: "Afflictions that give expression to volition must be predominant, and are therefore spoken of as wrong view." If discussing the three roots, they encompass both the middle and upper grades and do not extend to the lower grade, because minute and lower afflictions do not actuate karma. The three poisons are broader, subsuming all three grades. The doctrine of the three roots and so forth is briefly distinguished as above.
