Looking at the 3rd organising principle of the Polyvagal Theory: Hierarchy. No matter what state we're in, our nervous system is always ON, enacting a response to ensure our survival. There are 3 pathways each working in service of our safety, easily placed in a timeline starting from 500 million years ago: The Ventral Vegal (VVPS) Parasympathetic System, the Sympathetic System (SS) and the Dorsal Vagal Parasympathetic System (DVPS). The VVPS is a system of safety and connection where we have access to health growth and restoration (our HOME). The SS is our mobilisation response stata aka "fight or flight", where  protection is through action. Lastly, the DVPS is all about immobilisation, where we protect ourselves through disappearing and disconnecting. We can work through these states so that we can always find our way back home!
