Based on the Castoriadis theories about psycho-social- historical imagination and on the symbolic efficacy of Lévi-Strauss, this study aims to understand the motivation that lies behind the use of past live therapy. A research was conducted on the main authors in this field and a number of interviews were performed with patients, as well as with past live therapists. An analysis of their discourse revealed that this kind of therapy has been growing and ramifying in the most different technical variations. We noticed that this past live therapy is closely permeated by a series of spiritualists` beliefs and these beliefs makes its acceptance very hard among scientists and academics. On the other hand, the technique has become popular among therapists and patients, who have been more and more looking for this type of therapy.
