Life rehearsal?

It is difficult to describe the Method of Physical Action (here, MPA for short) in few words because it requires an understanding of the significance of physical action, or more specifically, in the performance of physical action. The idea behind the MPA is fairly simple per se, but its implications are profound. It is easy to oversimplify. It is based on an idea that always fascinated Stanislavski, that emotional life is a kind of two-way street; further, that the only thing an actor will ever have control of in his life as regards himself is his body, nothing more. There is never a direct line to emotions in performance, only to the body. Emotions may be remembered and brought up via emotional memory, but Stanislavski generally considered this if anything a rehearsal tool or technique of research, at best. There is, in the end, only the body.
