Just few days ago I travelled to "Peace of Light" event in Bali - where people from 5 continents and 27 countries gathered to perform traditional rituals for the peace of the world and vowed to take initiative to bring in the world. We ALL must do it together. Such events could be any where next. We need to learn how to handle our emotions and mind and teach them to others. In this regard I find Sri Sri Ravi Shankar's Art of Living programs effective, which has been transformational for even the most hard-core terrorists.
Let us all work together for peace in action and not just wishful thinking.
