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 life of a character should be an unbroken line of events and emotions, but a play only gives us a few moments on that line - we must create the rest to portray a convincing life.
Constantin StanislavskiIn every physical action, unless it is purely mechanical, there is concealed some inner action, some feelings. This is how the two levels of life in a part are created, the inner and the outer. They are intertwined. A common purpose brings them together and reinforces the unbreakable bond.
Constantin StanislavskiIn the circle of light on the state in the midst of darkness, you have the sensation of being entirely alone... This is called solitude in public... During a performance, before an audience of thousands, you can always enclose yourself in this circle, like a snail in its shell... You can carry it wherever you go.
