Hi Johnny, please keep the questions open so everyone can answer.
Yes. That is correct.
However, some of those are “secondary rupa”. The root cause is always the mind. So, javana citta are the one’s that really cause the whole world to arise, and it needs a deep analysis to cover fully. However, this is what is discussed at the “Nāma & Rūpa to Nāmarūpa” subsection.
However, here are the key points:
1. Cittaja rupa are the rupa or energies created by the mind in javana citta.
2.Those energies remain in the nama loka for a very long time, until their energies slowly run out. If suitable conditions appear they then bring vipaka via kammaja rupa. For example, at the cuti-patisandhi moment the hadaya vatthu and pasada rupa created are such kammaja rupa (kammaja means generated via kamma).
3. Cittaja and kammaja rupa give rise to utuja rupa. Utuja rupa have nothing to with “temperature” though. These are basically those rupa that we experience (material things).
4. Aharaja rupa are those created by a body during digestion, for example.
Therefore, kammaja, utuja, aharaja rupa all have true origins in cittaja rupa. This is why it is said that “mano pubbangama dhamma..” or “mind is the precursor..”.
