Pure Land Schools' version of the Three (or Four) Marks of Existence

I'd be grateful for references to some of the major Pure Land schools' versions of the Three (or Four) Marks (Seals) of Existence: - Impermanence (*anicca*) - Suffering (*dukkha*) - No-self (*anattā*) - Liberation (*nirvāṇa*) Addendum -- pointers to the individual topics in any Pure Land tradition would be fine -- does not have to be all together. Jan 6 -- beyond my own answer, with three references, I would still be grateful for further items, plus explanations of where the three marks (that is, the somewhat philosophical ideas so crucial to Theravada and Tibetan schools) fit into Pure Land in general, and on the specific texts I found.
