This article aims at presenting the rules for utilizing patient resources as a key strategy in Ericksonian psychotherapy. The concept of resource utilization under the Ericksonian approach and as defined by other schools of psychotherapy is outlined in the first part. Next, the strategy of resource utilization is explained and an individual short-term therapy case study, illustrating its practical application, is presented. The patient discussed in the case study was a 45-year-old man with adjustment disorders. Clinical hypnosis was used by the author to activate the patient’s access to his inner potential and resources. Through the use of hypnotic communication methods, the healthy parts of the patient’s personality were strengthened, including his ability to consciously identify his vital energy and integrate his internal, dissociated aspects. The patient discovered his own solution to the problem, gaining the opportunity to free himself from catalepsy and to proceed on a path of development. The described therapy process confirmed the author’s experience that change achieved in individual work with the patient creates movement and transformation in his social system.
