I said “For a sakadagami and up, is the perception reduced then by the weakening of both the mana cetasika and the avija cetasika as one progresses?”
I meant the perception of a “self.”
But I realize now that all these cetasika must contribute to that perception. As one loses these defilements, one starts seeing the truth of things at a deeper level, hence the weakening of that perception.
Though, avija and mana may have relatively more influence on the sense of a “self.”
