Here is something on Shin, with a bit of discussion on the individual topics -- http://www.nembutsu.info/primshin.htm -- plus this at the very end (emphasis added):

focus on the Buddha, the Dharma and the Sangha;

Does anyone know the significance of The Treatise on the Ten Doubts in Pure Land? I cannot find much online.
In -- The Sutra of Visualization of the Buddha of Infinite Life -- at http://www.fodian.net/world/365_sutra_1.htm III, VI, XVI -- here it is in III:
Pure breezes of the eight pleasing qualities are produced by these
rays of light, causing the musical instruments to play in voices which
proclaim the truths of ‘suffering, emptiness, impermanence and
non-self.’
Interesting that in these last two, emptiness is added to make 4 marks.
