“But a sotapanna removed nicca saññā vipallāsa.”
– That is not correct. But what I had in #18 of that post was not quite right either. I just revised that sentence (in #18) as follows:
“Saññā vipallāsa goes away at the Anāgami stage, and citta vipallāsa (together with asmi māna) is removed at the Arahant stage. See “Vipallāsa (Diṭṭhi, Saññā, Citta) Affect Saṅkhāra.”
