I second this. If you can look past the "Goenka dogma", these 10-day retreats offered around the world are a great way to experience life raw and without distraction of technology or otherwise, in meditation.
I agree about the fact they're a great opportunity to experience a unique lifestyle for the duration of one's stay. I've never felt calmer in my life than during the Vipassana retreat I did two years ago. But I'd advise anyone thinking of attending a retreat to look up critical opinions on the topic. I was personally put off by the sectarian vibe that I felt when I was there, much to my surprise. The method has its merits, but it is not scientific.
Yes, there is a bit of "bullshit" that goes with a Goenka course for want of a better word. The way I looked at it was the only reason I was being annoyed by it was because of my ego. Question why those aspects of the course bother you.
It makes sense to answer in terms of ego, and it's true ego plays a role. But the way this truth is used to shield away from tough questions is precisely what sounds sectarian to me.
