Yeah, agreed, there's a lot of misinformation. I'm always encountering people that say they just started, followed a guided meditation on the jhanas and entered fourth jhana within a week. And then the signs they describe are all just your basic things that arise when you first start having some facility over your practice, probably not even stability in the first jhana. Not to mention that it's impossible to be following a guided, external voice when you're in such a state of absorption.

As Chogyam Trungpa would probably say, they're all practicing spiritual materialism.
