金光明經文句記 3.44

3.44

二、「仁王」下，明五陰常住相。性名不改，即百界五陰八相莫遷、十方周遍，然非事底別有性陰，秖善惡陰穢污陰等當體常住，名法性陰。慎勿別求。

Second, from 'Benevolent King' downward, clarifying the characteristics of the permanence of the five skandhas. 'Nature' means unalterable: that is, the five skandhas of the hundred realms do not shift across the eight phases and are all-pervading in the ten directions. Yet it is not that beneath phenomenal matters there is a separate nature-skandha; simply, the wholesome, unwholesome, defiled, and polluted skandhas, in their very substance, are permanently abiding, named the Dharma-nature skandhas. Be careful not to seek them elsewhere.
