大方廣佛華嚴經隨疏演義鈔 24.13

24.13

疏「照第五藏令化令淨」者，以第五法界藏通因通果，外持一切染淨有為，名為法界；內含一切恒沙功德，故復名藏。以有因故化之，以有染故淨之，餘如前說。

Regarding the commentary's phrase “illuminating the fifth garbha, causing transformation and causing purification”: because the fifth, the dharmadhātugarbha, applies to both cause and fruit. Externally, it sustains all defiled and pure conditioned phenomena, and is called the dharmadhātu; internally, it contains all merits as numerous as the sands of the Ganges, and is therefore also called a garbha. Because there is a cause, he transforms it; because there is defilement, he purifies it. The rest is as explained before.
