Calm

Calm or calmness was an emotion and a state of mind.
When trying to prevent Sensorites from getting into his and his companions' heads, the First Doctor instructed them to remain calm, as calmness could increase their mental fortitude. Fear, on the other hand, would weaken their resolve and make them more susceptible to mind control. (TV: The Sensorites)
