大方廣圓覺修多羅了義經略疏 1.835

1.835

由前悟得根、識、塵、大，世出世間諸法皆歸實相清淨，方始成就。此人一身清淨，故諸段清淨，皆牒前文，唯此獨指實相以為淨之所以。

Because one previously awakened to faculties, consciousnesses, defilements, and elements, and all mundane and supramundane dharmas return to the purity of dharmatā, this is only then accomplished: this person's single body is pure. Therefore, the purity in each section takes up the previous text; only this alone points directly to dharmatā as the reason for purity.
