A smile is the beginning of peace; in acceptance, there is peace; a soft voice in our heart is the sound of peace and what not Peace is liberty in tranquillity.
It is in human constitution that one tends to be influenced by the power of nature, its ability to remain soothing and calm even in the midst of grievous storms; for even then the sun shines bright on every stone, the water bathes the spirit of all the sand off dirt and the sky yet wraps and protects them all from any harm. And it is thus even more relevant when we say that “You cannot find peace by avoiding life”.
Peace is not merely a five letter word that we imbibe within ourselves but it is our state of being. Peaceful is the real nature of humankind and war merely a substitute to maintain it – for even though soldiers might fight, and wars might commence and destroy yet the butterflies look beautiful to all living souls likewise. Hence peace is not something that can be contained in a random set of words that intend to define it but yes indeed it is an abstract entity that forms the essence of our lives yet remains unidentifiable on physical grounds.
And as one such naturalist once quoted: Peace is not something you wish for; it’s something you make, something you do, something you are and something you give away.” 
Therefore, peace is righteously a reward in itself and the utmost goal of everyone’s life. 
World Peace is a subject that has far gone a number of interpretations in itself to evolve to what it has become today. While a considerable part of the world defines it as the harmonious relationship between people despite all divisions of race, culture etc; there still is a part of the population that compares it with the extinction of wars and violence. And to rule out the righteousness of each is a grave offence. Peace is often found to be unanimous with the feeling of brotherhood among fellow citizens and in accordance it thus reduces the likes of wars and violence. So in these contexts it very well justifies the saying that “Peace is a noun that acts as a verb”.
But still we are well aware of an intellectual genius who once quoted: “Peace comes from within.  Do not seek it without”. And it is this that revolves around the central idea and definition of the term peace, contrary to the present assumption. Peace henceforth can be stated as a state of mental calm and sooth where one tends to un-prompt, prohibit and prevent all actions and thoughts that may be the cause of hurtful events. These are thus the three P’s of peace!! And it is when these three principles are employed to affect a large population of people all around the world that we symbolise it with the term WORLD PEACE. 
So like the magnanimity of the idea of being at peace – where everyone tends to call oneself peaceful until provoked to act unlike – the world portrays to remain at peace until it encounters rifts amongst its citizens. 
And it’s with effect that this defined portrait roots in our minds and follows our personal ideals of a peaceful world.
Yet there are people who dare to differ from this viewpoint. Buddha once said “The foot feels the foot when it feels the ground”. In other words he held on to fact that it is but the human itself that is the carrier, vector and messenger of peace.
He defined peace as a state of mind – mind which itself has no identity hence no boundaries and structure- which controls our state of being. Therefore, he pointed at the large extent of how these five letters’ word PEACE, spans our lives in all spheres- yet remaining unknown and unfelt.
Even the Hindu mythology describes the human body as a small sized depiction of the whole universe. In other words taken together all the religions of the ‘geographical’ world point to the fact that indeed it is, but the human body itself that is THE REAL WORLD.
And in the same context “world peace” yet begs to another spiritual interpretation. It leads to the idea that since the world is but within us, so it is but the peace of our own self that matters and makes a difference. And that is what I believe emulates as the meaning of world peace when we say that peace (world peace) cannot be achieved by force but by understanding. And in the same line, this understanding is but a result of our harmony with our thoughts and actions. 
For indeed everything can be stained
But not that inner voice,
And no one can be blamed but
Our own thoughts and our own choice!

 Therefore the world does aptly remain at unexpressed and unsought wars all the time, rifts amongst people continue to exist while a poet’s pen rages forward to write –
Until to what’s been set to wrong
Peace is rightfully done
We can hope well by seeing the darkness
Give birth to the sun….
