Bhagavad Gita, Chapter 18, Verse 27

He who is passionate, desirous of the fruits of action, greedy, malignant, impure, easily elated or dejected, such an agent is called Râjasika.

This performer is described here as genuinely pulled around, real joy and real sorrow both dictating their state.

Krishna names emotional volatility directly as a mark of this mode, not a personal quirk. Real instability, tied to craving results, defines this kind of performer.
