This quote by Ralph Waldo Emerson is a suggestion that peace is an internal state of being. It is not something that can be given to us by another individual or by external circumstances. We need to take obligation for our own comfort and emotional wellness. It is up to us to produce an environment of peace within ourselves, and to take the required actions to maintain it. This could consist of taking some time for self-care, engaging in activities that bring us delight, and discovering to accept and forgive ourselves and others. Ultimately, it is our own obligation to cultivate peace within ourselves and to ensure that it is not depending on external factors.
