The master thesis "Source Echo" is an exhibition-performative event. The idea is to scratch the essence of the human being that carries the identity of Ana Ilić through several months of work. The work deals with identification, the process of individuation and the transformation of individuals through art. The first part of the paper deals with psychology and the concept of identity. Then the similarities and differences between the concepts of theater, ritual and performance are emphasized. Critical analysis of reference art examples included the work of artists Pina Bausch and Yvonne Rainer, as well as the work of the dance groups Jacob Jonas The Company and Sankai Yuku. In the chapter on artistic research, the process of searching for a theme and the process of movement research through various psychotherapeutic methods are described. The product of the work on the art project is a dance performance and spatial intervention.
