Do not be too quick to get angry.

Contented mind, calm cheerful soul.

We can only be calm since God controls all circumstances.

Keep calm in crises.

Be calm in crises.

Calm in crisis.

Keep calm, God is still in control.

The brevity of life is the calmness of a courageous soul.

If we can only be still, we shall behold, the beauty of a still voice.
