… when you receive a shock, is to answer at once by this thought —”Let the Peace of the Lord be with you.”— Not in spoken words but clearly in your mind, and continue thinking of the Lord’s Peace and not of the unpleasant sensation — This is a good remedy and will minimise the bad effect. When you think of the Lord’s Peace it acts as a call, and the more you think of it the more you surround yourself with it which is the most powerful protection.
