Safety is not a thought. It is a physiological state, one that the nervous system enters or exits based on cues that the conscious mind may never register. Stephen Porges' polyvagal theory describes how the vagus nerve, the longest cranial nerve in the body, governs the hierarchy of defensive and social states that determine whether we feel safe enough to connect, alert enough to fight or flee, or so overwhelmed that the only option is shutdown. This fully referenced article explores the neuroscience of felt safety, why it cannot be willed into existence, and what conditions the nervous system actually needs in order to stand down.
