This is the second of three (3) posts about this experience, and it will be written in a Frequently Asked Questions (FAQ) format. If you aren't familiar with Vipassana, I suggest first taking a look at Part 1 (general overview, some logistical questions). If you find yourself interested after reading the first two posts, you can see Part 3 (advice for people who'd like to give it a go).
My partner did Vipassana together with me; here's Part 1 and Part 2 of what she wrote about her experiences.
