Brainwave Patterns in the Jhanas

Yeah, agreed. There are some problems here with this because there is such variety subjectivity with what is described as “jhanas”, and also assumptions about how such a process would/does work neurologically. I’m not sure it could be pinned down scientifically at all actually. I will say though, that the research done on the brains of meditators vs. non-meditators are quite intruiging.
