The book describes the history of the gestalt approach, examines classical laws of perception, and reveals the relational and holistic nature of the interaction between "person – environment". It explores topics such as contact boundaries, the relevance of awareness, the psychodynamics of self, and the importance of fully accepting oneself. Within the gestalt approach, it is emphasized that a person exists within complex systems (personal, social, and cultural), the environment shapes needs and interaction scenarios, and a safe therapeutic atmosphere is crucial for expanding the client's worldview. The authors focus on phenomenological studies of experience, existential approaches, body-oriented diagnostics, and intersubjective creation of new meanings. They also provide practical tools for assessing expectations and risks, step-by-step planning, monitoring the therapeutic process, forming a working alliance, and differentiating zones of awareness. The book details the stages of therapeutic work: from assessing the client's readiness for therapy to its completion. Exercises for self-implementation and self-reflection questions are presented. Special attention is paid to ethical aspects: boundaries, preventing manipulation, supporting the client and the therapist themselves.
