The cortisol protocol

I know when I am stressed about a situation that medically, cortisol and adrenaline are released.  There are exercises in learning to control the body's natural reactions to those hormones and the most effective one for me is a type of meditation.  My wife and I had the pleasure of attending the Outcry concert over the weekend and when Jesus Culture played "I exalt thee", I was lost in the thousands of people singing.  Especially when everyone repeated "I exalt thee" over and over.  It was a meditative, serene, calming, and powerful moment.  To me, it was a glimpse of what I can imagine heaven to be like.
