妙法蓮華經文句 4.107

4.107

準例邪正三毒，邪是五濁，正是五清，他方淨土無邪三毒，則五濁障輕，此義可知（云云）。

"By analogy with the deviant and correct three poisons: the deviant is the five turbidities, and the correct is the five purities. In the pure lands of other directions there are no deviant three poisons, so the obstacles of the five turbidities are light; this meaning can be understood (and so forth)."
