Between the two references of Peter Brook (1968), in which this reflection on the body of and in the group begins and ends, there is that empty, creative space, indispensable in the theatre as in the work of the Multifamily Psychoanalysis Group. In the background, the containing function of the group as of the choir in Greek tragedy. The reflection will be articulated around the pathogenic and pathological interdependencies underlying the relational patterns in different families (of a Roman DSM and the Centro Ditem in Buenos Aires), to arrive to metaphorical mirroring and multiple transference and countertransference within the gr
oup. The theory of J. E. G. Badaracco (1997; 2004) and references to the world of theatre will offer ideas for reflecting on clinical experience, allowing us to get to the “expanded mind”(Mente Ampliada) as a representative element of the group’s body.
