Interesting take on trauma as biological phenomenon

For all interested in trauma, PTSD, childhood abuse and body-mind connection – i stumbled upon the works of this guy http://en.wikipedia.org/wiki/Peter_A._Levine and must say i’m thouroughly fascinated by his fusion of evolutionary biology, animal study, spirituality, mythology, psychology and trauma research. if you web-search enough, there are 2 pdfs somewhat easily obtainable.
