大乘起信論義記 3.274

3.274

三者、聞修多羅說如來之藏無有增減，體備一切功德之法。以不解故，即謂如來之藏有色心法自相差別。

"Third, hearing sūtras say that the tathāgatagarbha has neither increase nor decrease and that its essence is equipped with all the qualities of virtue, because one does not understand, one then claims that the tathāgatagarbha possesses intrinsic differentiation between material and mental phenomena."
