Van der Kolk’s central argument is that trauma doesn’t just live in the mind, it lives in the body. Long after a traumatic event, the body continues to react as if the danger is still present: bracing, shutting down, overreacting. Talk therapy alone often can’t reach it. The book makes the case for body-based approaches, From EMDR, yoga, theater, neurofeedback, etc as ways to help the nervous system finally feel safe.
