Peace is not an absence of war, it is a virtue, a state of mind, a disposition for benevolence, confidence, justice.
Peace is not only better than war, but infinitely more arduous.
George Bernard Shaw
Those who are at war with others are not at peace with themselves.
Those who make peaceful revolution impossible will make violent revolution inevitable.
John F. Kennedy
To attain inner peace you must actually give your life, not just your possessions. When you at last give your life - bringing into alignment your beliefs and the way you live then, and only then, can you begin to find inner peace.
