i googled the definition of calm and this is what i found

Calmness is the mental state of peace of mind being free from agitation, excitement, or disturbance. It also refers being in a state of serenity, tranquillity, or peace. Calmness can most easily occur for the average person during a state of relaxation, but it can also be found during much more alert and aware states.
