Through the reflection on different processes of creation around the poetics of William Shakespeare's theater and the study of different cognitive models about image and imagination involved in my training and teaching processes, I review my own training framework as an actor and teacher, to understand how ideas about imagination and the use of different pedagogical tools influence the structure of the performer's imaginary universe. Also a review of different concepts and ideas about image/imagination within the Stanislavski system and the developments of some of his students. It is directed towards the actor's training, helping him to recognize his own imaginative poetics from the recognition of himself and his expression as a metaphor, with the purpose of enjoying his own universe of images as the expansion of his personal domain, to clarify its importance and to promote the relationship between his creativity and his work on stage.
