M.R.I. brain scans taken before and after the participants’ meditation regimen found increased gray matter in the hippocampus, an area important for learning and memory. The images also showed a reduction of gray matter in the amygdala, a region connected to anxiety and stress. A control group that did not practice meditation showed no such changes.

Within four miles of our Bay Area home, there are at least six centers that offer some type of meditation class, and I often hear phrases like, “So how was your sit today?”
