It is good to try to analyze/investigate like what you did. That is part of insight meditation.
- However, in this particular case, there is an aspect that we need to learn, which cannot be sorted out by using mundane ideas like elementary particles in science.
- Neva + saññā + nā + saññā means “they have saññā for a time period, but may not have saññā for a while.” As we know, saññā is a “universal cetsika” that arises with any citta. Thus, it means those Devas do not have cittas arising for brief periods (like in “full Nibbana” or like in an Arahant in “nirodha samapatti.”)
- As a lifestream proceeds up to the rupa loka and then to the arupa loka, one gets closer and closer to Nibbana (the “pabhassara citta.”) However, all anariyas, no matter how far upward they proceed, “fall back” to kama loka. That is because they have not broken any anusaya or samyojana.
- On the other hand, an Ariya proceeding up the jhana/samapatti ladder goes upward while breaking various anusaya and samyojana on the way. Thus, when they get to the Nevasaññānāsaññāyatana stage, they can get to “nirodha samapatti.” That can be done only by an ubhatovimutta Arahant.
