This is a Neuro-Sequential Model, created by Dr Bruce Perry, and illustrated by Beacon House, UK.
Physical and Emotional Pain... Fatigue... Can represent early struggles, and can be used as opportunities to heal parts of the brain and mind.
Instead of avoiding relationships, or circumstances, and environments or trying to control circumstances so that we don't have to feel as helpless as we once were, we are presented with an opportunity to resolve past stressful / traumatic experiences, by cultivating a 'relationship' with our different 'maps' and Parts. This internal relating and soothing has the power to transform our physical and emotional well being, our relationships and lives.
