What I didn’t understand is that kiriya citta can only occur in arahants. If so, I don’t know what to call a citta of puthujjana without sancetana. I thought it would be meaningful to get an answer on this topic because it would be an example of how Abhidhamma can provide answers to ‘anything.’
In Buddha Dhamma, there is one term “avyākata” or “abyākata” means “indeterminate or neutral” which you may have not understood.
You may want to check out the book “Guide Through the Abhidhamma Piṭaka by Ñāṇatiloka Mahathera” by searching the word “avyākata” and see the concern text related to “avyākata” within the seven books of Abhidhamma.
Hope this helps your undertanding on “neutral” action.
With mettā, Seng Kiat
