Namo Buddhaya!
Note here you define samadhi as a produced state.
In short,
- Pertubable samadhi is sankhara, a produced state attained in dependence on something constructed
- Impertubable samadhi are sankhara, a produced state attained in dependence on something constructed
- Cessation samadhi is a cessation of sankharā attained in dependence on the unconstructed.
Cessation samadhi as a cessation of sankharā attained in dependence on the unconstructed is however not the final goal of the training because this attainment is a means to an end of taints.
There is also the notion that attaining any samadhi & the narrative of doing anything at all describes a living being with name & form, of such or such family, etc.
Therefore whatever is attained by a mortal is in a sense impermanent as it is an event of him attaining it. Even if it is a cessation samadhi attainment.
However the talk of samadhi is one thing and that in dependence on what the samadhi is possible is another thing.
So all the talk of beings attaining things is a description of the inpermanent which ceases and that in dependence on what the cessation is possible, it is not impermanent.
Therefore when you say
The most excellent dhamma is not sannavedayitanirodha nor any jhana but Nibbana which is not some volitionairy produced state nor a samadhi nor a building that can desintegrate any moment
You should keep in mind that sannavedayitanirodha occurs in dependence on the asankhata, if there was no asankhata then sannavedayitanirodha wouldn’t be possible.
When you talk about beings attaining cessation samadhi you are essentially talking about approaching the unmade rather than the unmade because one who attains nirodha comes to know the unmade but this knowing & attaining is not the unmade as their knowledge & attaining is impermanent.
It is like if you go to a supermarket, the achievement of getting there is dependent on there being a supermarket and it is not the same thing as your approaching it. Albeit here the supermarket is a constructed thing.
The goal of the training is not this cessation samadhi, rather it is arahantship. And purpose of arahantship is dukkhanirodha. And parinibbana is the ultimate dukkhanirordha occuring in dependence on the same nibbananirodhadhatu as sannavedayitanirodha and so it’s all about the end.
Attaining sannavedayitanirodha is analogical to turning off everything at the end of a movie. The emergence from sannavedayitanirodha is then like starting to watch a sequel movie. This attainment removes taints and with the breakup of the body there is no sequel.
Another analogy is a rather famous one
Attaining sannavedayitanirodha is like a flame going out due to a gust of wind but where coals remain hot. And emergence from sannavedayitanirodha is akin to the coals blazing up again. And final extinguishment is where both the flame & the coals become completely cool.
Third analogy i can give is to seeing a mirrage.
The person attaining sannavedayitanirodha is like coming to after seeing a mirrage . Then emerging from sannavedayitanirodha is like seeing the mirrage again. And parinibbana is never seeing the mirrage again.
It’s a necessity.
- First a person has to take on faith that his predicament is that of being stuck in a persistent mirrage empty of substance.
- Furthermore he understands & comes to agreement through pondring that he finds himself being stuck in a persistent mirrage empty of substance.
- Furthermore he cultivates this perception of drawbacks & does not welcome being stuck in a persistent mirrage empty of substance.
- Furthermore there comes to be a cessation of the mirrage due to disinterestedness & dispassion. This is called ‘an awakening to the truth’.
Further he either emerges as an arahant or has to keep seeing the truth by repeated attainment until his taints are removed by the seeing with wisdom as development of these qualities is a final attainment of truth.
