Hello
I’m surprised that you posted what you posted under the meditation label. Unless this school here equates bhavana (contemplation) to meditation. Personally i equate Dhyana/Jhana to meditative absorption through singlepointed focus on a concept (arya jhana) or through a kasina object which understands breathing too, and then it’s called anarya jhana because it doesn’t implie (apparently at least) objective insight. This said it’s an interesting contemplation yours.
