People have all sorts of notions about meditation. I'm writing for people who have become intrigued by the potential insights gained by psychedelics -- who may even be seeking relief from existential anxiety right now -- but may still have some doubts about using psychedelics. These folk are unlikely to to know what "vipassana" is, or that it is a meditation, or that there are lots of other things people call "meditation", and most importantly, a Google keyword to look through.
If you know enough to nitpick this, then you probably didn't need the information :-D
== another nit: the first word is a useless adjective.
