Never lose yourself on the stage. Always act in your own person, as an artist. The moment you lose yourself on the stage marks the departure from truly living your part and the beginning of exaggerated false acting. Therefore, no matter how much you act, how many parts you take, you should never allow yourself any exception to the rule of using your own feelings. To break that rule is the equivalent of killing the person you are portraying, because you deprive him of a palpitating, living, human soul, which is the real source of life for a part.
Constantin StanislavskiThe character has to have some kind of arch. The character has to go through an event, and be changed by the human event.
Constantin StanislavskiAll action in theatre must have inner justification, be logical, coherent, and real.
Constantin StanislavskiIn the creative process there is the father, the author of the play; the mother, the actor pregnant with the part; and the child, the role to be born.
