Grief has long been understood primarily as a domain of care rather than therapy: a natural response to loss that unfolds over time, with the supporter's role being to accompany the process rather than to intervene in it. Even the Continuing Bonds framework (Klass, Silverman, 人格移動) is proposed as a structured grief therapy method for such cases. Within the rational optimal zone of the Three-Layer Rational Consciousness Zone Theory, PST guides the bereaved client to experientially inhabit the perspective of the deceased from the inside, generating the prediction error that enables relational memory to be updated. Three clinical cases are presented demonstrating that PST can loosen fixed relational understanding and allow the continuing bond with the deceased to be felt in a new form.
