首楞嚴義疏注經 4.416

4.416

生滅是行，行即是業，眾生執愛但欲留住，業性遷流每常運動，一去一住、一動一留，互相交織，眾法生滅，名眾生濁，即造業相也。

Arising and ceasing is conditioning (saṃskāra); conditioning is karma. Sentient beings grasp and crave, wishing only to remain; the nature of karma drifts and constantly moves. One departing and one remaining, one moving and one staying, they intertwine with each other, and multiple dharmas arise and cease; this is called the turbidity of sentient beings, which is the mark of creating karma.
