3.157

十三、一切身業隨智慧行。佛先知，然後隨知起一切身業，故有所現處無非佛事，利益一切，故名身業隨智慧行。

Thirteenth, all physical karma follows knowledge. The Buddha first knows, and only then initiates all physical karma in accordance with that knowledge. Therefore, wherever he manifests, there is nothing that is not a Buddha work, benefiting all beings. Hence it is called physical karma following knowledge.
