Brain Waves

In the map of brain wave activity below you can see that so-called higher brain activity is marked by a higher frequency whereas mystical states of insight are marked by a very slow vibratory frequency of brain wave patterns. I don't feel that one is preferred over the other necessarily, as it seems to me that we need variety....mystical states followed by rapid brain activity perhaps as a way to learn how to integrate the experience into our larger lives. Its an interesting chart.  I hope it helps....
