Here, I’ve learned that achieving ariya/anariya jhana is anantarika kamma.
However, before I met puredhamma, I had heard that cuti patisandhi into brahma is possible only when jhana is maintained until the very end of death.
I think this is a misunderstanding that occurred because they didn’t understand the concept of gandhabba.
So, one who attain anariya jhana doesn’t need to maintain jhanic state when he/she is at the close to death. Because anantarika kamma has already occurred.
Therefore, even if one had attained jhana ONLY ONCE in a given jati and then never entered jhana after that moment, it is still enough to rebirth at brahma realm. Right?
