Concept:
The use of masks in theatre transforms the performer from an individual into a universal or archetypal character. Masks carry their own inherent dramatic energy and "speak" through their design.
Step 1: Analyzing the physical act of masking.
The assertion is true because in many traditional theatre forms, the actor’s primary tool—the face—is physically obscured by a mask. This forces the actor to rely on body language, gesture, and voice to communicate.
Step 2: Understanding the communicative power of specific masks.
The reason is correct and provides the logical justification for the assertion. Forms like Chhau (India) and Balinese theatre (Indonesia) use masks that are so intricately designed that they represent fixed emotional states, deities, or spirits. The mask "suggests" the character's soul on its own, allowing the actor to become a vessel for that established image.
