Actually, it’s your problem.There is no blissful and continuous Self/self (atta) - like Ka - in the salayatana nidana and below.
Is that hard to understand.
I don't care about what the "materialists" thought. That's your problem.
I’m aware of how the Vedas imagine self. I’m also aware that the Buddha didn’t grow up in a Vedic culture and didn’t exclusively teach in a Vedic culture, and that other soul theories were around (such as the Jains, Ājīvikas and the materialists). Regardless, the Buddha seemed to be critical of any self theory be it divine or not, in any way it’s conceived, in any world or context. Why? Because any view of a self comes from craving and clinging. That isn’t a denial of course, in terms of a view. It’s not “verily there is no Self/self”. It’s an abandoning of self views through seeing their origination.Now learn about Self/self in the Veda. Maybe you'll find that Buddha didn't deny a Self/self, or a Self outside that range - or maybe not.
I’m glad you are able to see your own shortcomings. This is good.I am too much of an amateur to help you on that matter.
