“…The combination of light and tactile manual bodywork with non-directive verbal guidance is triggering the dyadic bodily resonance described by several authors as being deeply healing, restoring and resourcing ( Totton, 1998 , 2005 ; Levine, 2005 ; Bloom, 2006 ; Ogden et al, 2006 ; White, 2006 ; Heller, 2012 ; Cipolletta, 2013 ; Van der Kolk, 2014 ; Cornell, 2015 ; Payne et al, 2015 ). Trying to grasp the underlying mechanism of this beneficial process of EBW, research mostly points at optimizing and rebalancing of a secure attachment ( Ogden et al, 2006 ), at opening up the social engagement system ( Porges, 2009 ), at engaging and integrating preverbal memories ( Bloom, 2006 ), at befriending the body, which is a metaphor for allowing and naming the physical sensations beneath the emotions ( Van der Kolk, 2014 ) or at biological completion ( Payne and Crane-Godreau, 2015 ; Payne et al, 2015 ). The latter authors are putting forward a hypothesis for understanding body mind therapies as normalizing what they call a preparatory set, which is basically a unitary trauma response based on affect, posture and muscle tone, autonomic state, attention, and expectation and which they call the core response network.…”
