I go many times a week to a Vipassana meditation hall near my house. It is based upon mindful meditation. We do have mindful meditation sessions for people in 12 step recovery, but I can't say as that I have attended more than once. I prefer instead a non-divisional, inclusive approach to life in general, and don't really practice the 12 step philosophy, so I attend the other meditation sessions. But i love it! have been going for 2 years now!
