It's great that you were able to have such positive experiences and insights with so little practice. Perhaps like-minded LW-folk can as well? (ETA: I'm thinking that people with strong introspection skills might be able to make significantly faster progress.)

You importantly note that we may be able to avoid the long hard path others have had to take:

Neurofeedback, isochronic beats, and transcranial magnetic stimulation all seem like potential paths towards easy Enlightenment. (The jhanas seem to allow strong clarity of mind where drugs do not; but it is possible that being on drugs as much as possible might also be an interesting path. I'd rather not go down it yet.) 'Course, we might still have to just do it the hard way.

Part of my motivation for thinking about vipassana meditation is to figure out if there is an easier path. I haven't had any significant ideas about this yet though.
