Would ego be in the vinnana? While avija is the fuel or cause of ego.
One of the reasons why I say this is because Vinnana is taught as “our future expectations and hopes we have for this world”. We have these expectations and hopes because of avija. Having expectations, hopes, etc . . . as long as one thinks this way, to me it seems like one will always have the view of a “self” or ego in this thinking process.
As well, at Arahant stage, one gain’s Samma Nana, to me Samma nana is the key to remove avija and mana. An Arahant would still have vinnana until death of the body, but they would no longer be fooled by the vinnana and avija. They would truly see this world as it is.
