The main factor in any form of creativeness is the life of a human spirit, that of the actor and his part, their joint feelings and subconscious creation.
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.
Constantin Stanislavski
