Waking the Tiger

Peter A. Levine sets out a clinical model in which trauma is a physiological event rather than a disorder of the mind alone. Drawing on ethology, he notes that wild animals routinely face mortal threat yet seldom carry lasting symptoms, and asks why humans so often do. His answer rests on the nervous system: a high survival charge that was mobilized but never fully discharged, and the tracking of bodily sensation as the way through it.

For a clinician, the book supplies a working vocabulary. It names the felt sense, sets out how to move attention through sensation in small steps, and reads symptoms as responses seeking completion rather than pathology to be suppressed. Case material and structured exercises show the method applied to accidents, assault, invasive medical care, and early loss.

Levine wrote it for practitioners and general readers together, and it helped establish the body-centered approach he went on to formalize as a training.
