This is one of the reasons Baltimore Drum Church uses drum circles for shamanic journeying. One must free themselves of their personal demons in order to walk with gods. Drumming subtly forces you to live in the moment or enter a flow state. Upon entering a flow state the brain shifts from the normal beta wave view of reality to an Alpha/ Theta wave deep meditation state just through the act of participation. This flow state always creates a positive experience on the mind by stripping away obsession on the future and the past and resets the brain to the eternal now.
