大方廣佛華嚴經隨疏演義鈔 26.39

26.39

疏「二唯約住劫之中居人善惡」，復有二義：一約眾生引因所得；二約菩薩居中作用，心純善故，染淨交徹耳。

Regarding the Commentary's statement 'the second is solely with respect to the good and evil of the inhabitants during the kalpa of abiding,' this again has two meanings: first, with respect to what is obtained through the contributory causes of sentient beings; second, with respect to the activities of the bodhisattvas dwelling therein, because their minds are purely good, defilement and purity interpenetrate.
