第十一明佛變德遠生他福。問意如來法身及自受用身眾生不能見聞奉事，於諸有情有何因緣。答中，景云：如來是彼增上所緣之因緣，故遠生他福。又彼化身，是如來力所住持者，近由受用身起於他身，遠由法身住持化身，故彼二身亦生他福。

Eleventh, clarifying that the Buddha's virtue of transformation remotely generates merit for others. The intention of the question is: since sentient beings cannot see, hear, or attend upon the Tathāgata's Dharma body and self-enjoyment body, what causal condition do they provide for sentient beings? In the answer, Jing says: The Tathāgata is the causal condition of their sovereign objective support, hence remotely generating merit for others. Furthermore, that emanation body is sustained by the Tathāgata's power; proximately, it gives rise to the other body by means of the enjoyment body, and remotely, the Dharma body sustains the emanation body, so those two bodies also generate merit for others.
