This likely couldn’t convince the mahayana practitioner.
They think once the conceptual overlay is gone, suffering is gone there, but the phenomena still goes on, even after parinibbana.
They think we haven’t break through to emptiness insight, thus thinking that even the phenomena, 6 sense contacts must pass away after parinibbana, that the difference between arahant still living and dead arahant is really cessation not just another step and phenomena rolls on.
Hard to get through to these people, maybe it’s not worth it. Wrong view is so dangerous… but then could their view be qualified as wrong view? Not liberated, thinking they are liberated… hmmm… yes likely.
