大乘百法明門論開宗義決 1.170

1.170

或計自在等是一切物因者。執自在天能生諸法。等即等取大梵王等。亦是世間一切物因。即是自在所作宗也。

As for "or grasping that Īśvara and so forth are the cause of all things": they grasp that the god Īśvara can generate all phenomena. "And so forth" includes Mahābrahmā and others, [holding that they] are also the cause of all things in the world. This is the doctrine of creation by Īśvara.
