 These distinctions accord with widely held moral instincts, but the Abhidharma philosophers needed a full, causal explanation for why the successful results of physical actions bring about their distinctive effects in one’s consciousness. I can see how my plunging a knife into someone affects him; but how his dying (which may happen later, in the hospital) affects me is invisible, or uncognized. How does what goes around, come around? The Vaibhāṣika answer is that, since his death is a physical event, there must be another physical event—the invisible physicality—which impinges upon me.
