This seems partial, tendentious :”This is an important point. This is the reason that most people in the West have a hard time getting into jhana. On the contrary, there are many people in the East who can get to anariya jhanas. This is mainly because those in the West are heavily influenced by modern science and thus dismiss rebirth (and laws of kamma) as nonsense, which of course belong to 10 types of micca ditthi.”
There are more western people than you might imagine getting into Jhana. Some of them “believe” (wondering if it’s a matter of just “believing”) in rebirth others not.Even if the feeling of rebirth eases the access to Jhana, it cannot be an indispensable requirement to attain it.
This said i’m not affirming that i don’t believe in rebirth.On the contrary.
