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, tranquility, 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. Some people find that focusing the mind on something external, or even internal, such as the breathing, can itself be very calming.
