大般涅槃經義記 7.39

7.39

Third is clarifying permanence and impermanence with respect to the mark of arising. One should know that this arising is also permanent and impermanent, as explained in the text below. In terms of the scope of phenomena, alongside dharmas such as matter, there is constantly this arising; hence it is called permanent. In terms of the scope of dharmas, this mark of arising rises and falls moment by moment; once it has passed away, it never appears again; hence it is called impermanent.
