The Dalai Lama Speaks

"Peace, in the sense of the absence of war, is of little value to someone who is dying of hunger or cold. It will not remove the pain of torture inflicted on a prisoner of conscience. It does not comfort those who have lost their loved ones in floods caused by senseless deforestation in a neighboring country. Peace can only last where human rights are respected, where people are fed, and where individuals and nations are free." -- The XIVth Dalai Lama

This illustrates the thought process of focusing on all the things that require our attention, constantly working hard, striving, making it through our days with many of our own difficulties, pains, and suffering, and then we refocus and look at the entire world, and wonder, where do we even begin?

The question doesn't really require an answer. We simply do what we can, with our thoughts, words, and actions.
