Thank you very much for sharing this such a wonderful prayer from the great Lama Gangchen Rinpoche.
Buddhism teaches that whether we have global peace or global war is up to us at every moment. The situation is not hopeless and out of our hands. If we don't do anything, who will? Peace or war is our decision. The fundamental goal of Buddhism is peace, not only peace in this world but peace in all worlds. The Buddha taught that the first step on the path to peace is understanding the causality of peace. When we understand what causes peace, we know where to direct our efforts. No matter how vigorously we stir a boiling pot of soup on a fire, the soup will not cool. When we remove the pot from the fire, it will cool on its own, and our stirring will hasten the process. Stirring causes the soup to cool, but only if we first remove the soup from the fire. In other words, we can take many actions in our quest for peace that may be helpful. But if we do not first address the fundamental issues, all other actions will come to naught.
The Buddha taught that peaceful minds lead to peaceful speech and peaceful actions. If the minds of living beings are at peace, the world will be at peace. When the causes are identified, the Buddha's suggestions for dealing with them and eliminating them can be discussed. Finally, having developed a Buddhist theoretical framework for understanding the nature of the problem and its solution, we can try to apply the basic principles in searching for concrete applications that we can actually put into practice in our own daily lives.
