user471: What is the difference between the terms kamma and kiriya / kriya?
What is the difference between kiriya and kriya?
Please provide references to kiriya / kriya from the Pali suttas.

user22034: An extended discussion with Bhante Ariyadhammika, former Bhante Varado and Upasaka Sadhamma on the topic might enlighten till release from doubts, if not just after amassing (of course plenty of references incl. anyway): 'The Kamma of Arahants'!!, good householder. It needs care and much attention to get through the net rightly.

user10100: KiriyaCitta is KusalaCitta of Arahanta (Arahants' wholesome-mind) because Arahanta can't do any Karma which effecting next life anymore.

Katamañca    puṇṇa   kammaṃ   akaṇhaṃ   asukkaṃ   akaṇhaasukkavipākaṃ    kammakkhayāya     saṃvattati
What is neither-dark-nor-bright kamma with neither-dark-nor-bright ripening that leads to the exhaustion of kamma?

You should read MN Kukkuravatika Sutta, and AN  Kammavagga in detail.
Also Sankhara is depending on Avijja, and  KammaBhava is depending on Tanha, Arahanta has no Tanha, so his new karma has no  next-life-resultant.

Iti kho udayi tanhakkhaya kammakkhayo kammakkhaya dukkhakkhayoti.
And so, Udāyī, when craving ends, deeds end; when deeds end suffering ends.”

According to commentary, Abhidhamma was authored by ven. Sariputta (AggaSavaka), follow to the brief teaching of the Buddha, so it is ven Sariputta's writing style which is proper for the very in detail of Abhidhamma's contents, too deep and too specific for normal word.
Whole Tipitaka come out from 4th Jhana-Mastery's mouth, especially from Arahanta-Jhana-Mastery. Every 4th Jhana-Mastery has photographic memory and super unnatural mind speed.
So, it is normal if the ordinary people can't see the realities arising and vanishing super fast and super small follow Abhidhamma and many Suttas because only very few people can do only  sitting meditation whole days for at least 6 months to 5 years to get 4th Jhana Masery and high level insight meditation.
