Hello @Jasudho, hope you’re doing well!
But this understanding of Attā is based on actual experiences by meditators:
It’s when some ascetic or brahmin—by dint of keen, resolute, committed, and diligent effort, and right application of mind—experiences an immersion of the heart of such a kind that they recollect their many kinds of past lives. That is: ten eons of the cosmos contracting and expanding; twenty, thirty, or forty eons of the cosmos contracting and expanding. They remember: ‘There, I was named this, my clan was that, I looked like this, and that was my food. This was how I felt pleasure and pain, and that was how my life ended. When I passed away from that place I was reborn somewhere else. There, too, I was named this, my clan was that, I looked like this, and that was my food. This was how I felt pleasure and pain, and that was how my life ended. When I passed away from that place I was reborn here.’ And so they recollect their many kinds of past lives, with features and details.
They say: ‘The self and the cosmos are eternal, barren, steady as a mountain peak, standing firm like a pillar. They remain the same for all eternity, while these sentient beings wander and transmigrate and pass away and rearise. Why is that? Because by dint of keen, resolute, committed, and diligent effort, and right application of mind I experience an immersion of the heart of such a kind that I recollect my many kinds of past lives, with features and details.
So this understanding of an eternal soul/self didn’t just pop up out of the blue or happen to be some form of speculation. Rather, the eternalists misapprehend their experiences from immersion and their standpoints are rooted in feelings.
This is how The Buddha refutes eternalism:
“This, bhikkhus, the Tathāgata understands. And he understands: ‘These standpoints, thus assumed and thus misapprehended, lead to such a future destination, to such a state in the world beyond.’ He understands as well what transcends this, yet even that understanding he does not misapprehend. And because he is free from misapprehension, he has realized within himself the state of perfect peace. Having understood as they really are the origin and the passing away of FEELINGS, their satisfaction, their unsatisfactoriness, and the escape from them, the Tathāgata, bhikkhus, is emancipated through non-clinging.
Also regarding feelings and ”This was how I felt pleasure and pain, and that was how my life ended.”
They say:
- And though these beings roam and wander (through the round of existence), pass away and re-arise, yet the self and the world remain the same just like eternity itself.
So eternalists also happen to have neutral feelings regarding the suffering/pain involved in death and rebirth:
If they feel a neutral feeling, they feel it attached.
They’re called an unlearned ordinary person who is attached to rebirth, old age, and death, to sorrow, lamentation, pain, sadness, and distress; who is attached to suffering, I say.
- So the perception of a permanent self/soul that wanders from one existence to another is something plenty of meditators can experience as an actual reality and from that draw conclusions.
To uproot craving, feelings have to be uprooted:
When asked, ‘Is there a specific condition for craving?’ you should answer, ‘There is.’ If they say, ‘What is a condition for craving?’ you should answer, ‘Feeling is a condition for craving.’
‘There is such an attainment where the one who enters it does not feel anything at all.’” - MN 136
“Reverends, extinguishment is bliss! Extinguishment is bliss!”
When he said this, Venerable Udāyī said to him, “But Reverend Sāriputta, what’s blissful about it, since nothing is felt?”
“The fact that nothing is felt is precisely what’s blissful about it.
‘Reverends, when the Buddha describes what’s included in happiness,
he’s not just referring to pleasant feeling. <——
The Realized One describes pleasure as included in happiness wherever it is found, and in whatever context.’”
Of the seven types of annihilationists, six of them believe in rebirth.
Only the materialist-annihilationist who denies rebirth imagines a total annihilation at death.
That being said the semi-eternalists and the six types of annihilationists who believe in rebirth, have a lot in common.
