Everything that dies — cells, bodies, relationships, civilisations — dies the same six ways. Echo (turning inward), Rigidity (hardening), Fracture (snapping), Drift (losing coherence), Oscillation (unstable cycling), Overload (too much signal). These aren't metaphors. They're the same physics at every scale, because life is membranes holding gaps open against entropy. Death is the cascade that closes them. The book follows this framework from autoimmune disease to empire collapse, then into stranger territory: truth and death as the same direction, consciousness as the interference pattern of nested gaps, and mystical traditions as field reports on membrane architecture.
