Do you have any kind of medical backup for your claims about chakras? I know the basics of what they are supposed to be, but I did not exactly study them in any of my biology or psychology classes.

What I do know is that good quality heavy metal, like other forms of rock music, can create a very positive feel good mental state without harmful drugs, which science says is really good for people emotionally and, as a result of the emotional effects, physically. If your counter to that is stuff about chakras, I am curious to know where you are getting it.
