Vipassana is an absolutely wonderful experience. A 'brain washing' where it can rid your mind of all the crud that has accumulated from our culture and society. It puts you in touch with your body in a way that nothing my life ever has. I'd be happy to answer some questions if anybody has any.
Do I have to learn how to meditate before I go? How can I learn? Where do I find a place like this? If I want to do this, what are my first steps?
The analogy I'd give is if I'd joined a 10 day fitness camp and the only instruction was "do deadlifts", and then you were left alone for 11 hours. What's a deadlift? Is this the right form? After an hour I feel like I've exhausted these muscles, do I really just keep doing it for ten more hours today?
After three days of this, (each day having a slightly more specific focus but still lacking in the kind of direction or confirmation I was looking for), I left. I was a stone's throw from the Himalayas, and I felt that spending my remaining time in the mountains would do more for me than sitting in a dark room feeling confused and frustrated.
I can't answer how to learn to meditate, I haven't followed it up (once burnt, twice shy). But you could try the vipasana way at home - sit in a quiet room and "feel the breath entering your nose" for an hour.
