Create a scene in your imagination. Think of a scene - real or imaginary, from any time - that creates feelings of safety, warmth, security and peace, with no uneasy feelings. Make it vivid by feeling the breeze and the temperature, picturing the colours and hearing the sounds. Practise visualising this scene as often as you can. When you want to feel calm, think of this scene and stay imagining it for a short while. Then return your thoughts to the matter in hand. The sense of calm should stay with you and enable you to cope better with whatever comes.
