Atta is a type of paññatti (unreal), that can not force anything, but puthujana thinking wrong, by Sakkaya-ditthi, as "Atta is real. Atta have their power to force something. Atta can live forever, never die".
Anatta is real. Everything is anatta. Nothing have a real power. Everything can arise because of paccaya (factor).
Sakkaya-ditthi (self view) is cetasika, that thinking wrong "Atta is real. Atta have their power to force something. Atta can live forever, never die". Sakkaya-ditthi must arise together with lobha cetasika (desiring in atta).
Mana (pride/faze) is cetasika, that thinking "Self/Self-relating khandha are difference from another khandha. Although each khandha are difference from the other khandha, but every khandha are the same as "anicca, dukkha, anatta". Self/Self-relating is not the only one, that difference or being "anicca, dukkha, anatta".
Mana maybe not wrong as Sakkaya-ditthi. But it also arising with lobha, too.http://unmixedtheravada.blogspot.com/20 ... -mana.html
