"For all drama creates bondage," suggests that drama inherently involves some form of restriction or limitation. The very nature of dramatic performance binds actors, characters, and even audiences within certain frameworks, expectations, and roles that define the narrative and emotional experience.
"And the actor is only significant to the degree that he is bound," emphasizes that an actor's importance depends on their ability to embody and adhere to these constraints. Their effectiveness lies in their capacity to be bound by the script, character, and context, which ultimately lends meaning and impact to their performance.
