Both psychoanalysis and spirituality delve into a sacred space: the interior of the human being. In these pages, Roberto Longhi shares his psychoanalytic experience and points out suggestive affinities between psychoanalysis sessions and meditation, integrating different polarities: two subjects (me and not-me), two mediations (word and silence), two states (fullness and emptiness). Although at the beginning psychoanalysis and meditation are in a relationship of complementarity and simultaneity, a translation ends up taking place: from psychoanalysis to the spiritual.
