I’m not able to edit the post, but for #2. I wanted to add
#2 In order for us human beings to experience vipaka vinnana, does that person citta “always” have to evolve through the 9 stages of a citta to the end of vinnanakkhandha in order to experience vipaka vinnana or is there another way where someone can experience vipaka vinnana without that persons’ citta evolving all the way to vinnanakkhandha?
