What is peace?

This forum will discuss matters related to peace in Sri Lanka. First of all lets open the floor for a discussion on the fundamental question "what is peace, and how can it be maintained in a world of conflicting human endeavors, aspirations, and rituals?" Even in a family, there are daily instances where peace is broken. But peace is re-built through various natural mechanisms like sitting down together for dinner, breakfast, or lunch, shopping together, etc. Can these simple forces that re-builds peace be extended to large scale confilicts that are new and old? Can the mechanisms that are applicable to relatively new conflicts be applicable to relatively old conflicts?A discussion on these fundamentals would help us to bring and maintain peace in Sri Lanka.
