首楞嚴義疏注經 10.104

10.104

無盡流，行陰也，今見行遷，却執於我。死後有相者，以行是我所有故，行既遷流不息，故我死後有相也。

The 'endless flow' is the aggregate of formations; now, seeing formations in flux, he conversely clings to a self. 'Having characteristics after death': because formations are what the self possesses, since formations flow on without ceasing, the self has characteristics after death.
