To Lal #13199;
You say,
one removes all micca ditthis only when attaining the Arahant stage.
Now, that you have published the very detailed post on vipallāsa, I would assume that this is wrong. Whatever upādāna sottapana has after phala is due to vipallāsa saññā and vipallāsa cittā, but not due to MICCHĀ DIṬṬHI. right?
