瑜伽論記 21.131

21.131

泰云：如來者是受用身智慧，由智慧故，化為色聲，以如來色聲為增上緣故，眾生心識有似如來色聲相起，正是所緣如來色聲，但是增上所緣，非親所緣，如來智慧是彼增上所緣之因緣也，以親能變現為色聲故。

Tai says: The Tathāgata refers to the wisdom of the enjoyment body. Because of this wisdom, it manifests as visible forms and sounds. Since the visible forms and sounds of the Tathāgata serve as the predominating condition, there arise in the minds and consciousnesses of sentient beings representations resembling the visible forms and sounds of the Tathāgata. The actual cognitive object is the visible forms and sounds of the Tathāgata, but these are only the predominating cognitive object, not the direct cognitive object. The Tathāgata's wisdom is the causal condition of that predominating cognitive object, because it can directly manifest into visible forms and sounds.
