瑜伽論記 2.304

2.304

Under "If one takes only Great Maheśvara as the cause...": Great Maheśvara has existed from beginningless time, and the produced dharmas would also be established from beginningless time; therefore, it is not that Maheśvara can produce all dharmas. Just as the two horns of an ox arise simultaneously, [making] one a fruit and one a cause contradicts correct reasoning. Thus fascicle fourteen of the Prakaraṇāryavācā says: "Just as the substance of Maheśvara is inherently permanent, so too is the world; it should not be born anew. Because they are coexistent, there is no use in being newly born."
