Just wondering if anyone here has tried Holotropic Breathwork? It is basically the use of the breath and meditative music to enter an altered state, where much healing takes place. A friend of mine (also a Vipassana meditator) has tried this technique, and found it very powerful and quite helpful.
You can find more info here:

I'm considering doing a workshop pretty soon, so if anyone has any advice or experience, it would be nice to discuss!
