How much "Mahayana abhidharmic literature" can there be?
I don't know exactly ....
By name, only the Abhidharma-samuccaya comes to mind. Or do you refer to the northern Sarvastivada / Vaibhasika etc. Abhidharma literature, eg. the Kosa?
I do mean Vasubandhu's Abhidharmakosa + Asanga and other Mahayana writers detailing Buddhist "psychology", working of phenomena, etc.
