Welcome to the forum, puthujjana!
I think you brought out a key point.
Siebe says: “The most obvious views for me are full identification…”i am rupa, vedana, sanna, sankhara and vinnana”.”
This is correct. The five aggregates (khandhas) is all “a person” is defined by.
However, the key is to understand that “that person” does not have control over them.
All those arise according to Paticca Samuppada (PS), starting with “avijja paccaya sankhara”.
– You can verify that all those five are in the PS cycle. One’s own body (part of the rupa aggregate) arises via the “bhava paccya jati” step.
As long as one acts with avijja (i.e., without the comprehension of Four Noble Truths and Tilakkhana), one will keep generating those five aggregates and be subjected to suffering.
– The problem is that we are blinded by intermittent bouts of pleasure (especially when born in the good realms).
– When one is born in “bad realms” (like the animal realm), one can experience the harsh sufferings, but then one is not CAPABLE of tackling the problem.
– That is why we are trapped in this suffering-filled rebirth process.
This is also why the Buddha said that there is no “self” who has CONTROL over the five aggregates (khandhas).
– When one acts with avijja, the five aggregates arise automatically, based on the PS cycle.
The only way to get out of this is to cultivate panna (wisdom) by following the Noble Path.
– When one starts acting with wisdom, one will be following the “Kusala-mula PS process” that will lead to eventual liberation from any suffering.
– The first step is to stop births in the apayas where the suffering is worst, and that is accomplished by getting rid of sakkaya ditthi and becoming a Sotapanna.
– Put it in another way: five aggregates corresponding to animal or other lower realms would not arise via the PS process after one becomes a Sotapanna.
This is a deep point that needs to be thought about carefully. I am still working on my promised post on Sakkaya Ditthi; I am thinking about how to express this as simply as possible.
It would be fruitful to focus on this point.
