妙法蓮華經玄義 8.11

8.11

訓者訓常，今釋其訓。天魔外道不能改壞，名為教常。真正無雜，無能踰過，名為行常。湛然不動，決無異趣，名為理常。又訓法者，法可軌，行可軌，理可軌。今直釋訓已含六義，況胡言重複，而可單翻耶？

Etymologically, it is defined as "constant" (*cháng*); we now explain this definition. That which heavenly demons and non-Buddhists cannot alter or destroy is called the constancy of teaching. That which is genuine, correct, and unmixed, and which none can surpass, is called the constancy of practice. That which is calm, unmoving, and definitely without divergent destinies is called the constancy of principle. Furthermore, it is defined as "standard" (*fǎ*): the teaching can be a model, practice can be a model, and principle can be a model. Now simply explaining its definition already contains six meanings, so how could the repeated Sanskrit word be translated by a singular one?
