Abstract
We are interested in the kind of well-being that can occur as a person approaches death; we call it "existential maturity." We describe a conceptual model of this state that we felt was realized in an individual case, illustrating the state by describing the case. Our goal is to articulate a generalizable, working model of existential maturity in concepts and terms taken from fundamentals of psychodynamic theory. We hope that a recognizable case and a model-based way of thinking about what was going on can both help guide care that fosters existential maturity and stimulate more theoretical modeling of the state.
