Have not experimented with crystals but am interested to see in the Millennium what they are really about. There has to be something there since various types of crystals are used to amplify radio waves and other types of things.

I have heard really not good things about rebirthing. (I am a mental health professional) I think a lot of the theory is contrary to the teachings of the gospel.

I have seen lots of people have success from cranio sacral work. I think it helps the body rebalance and heal itself.
