When we can keep alive even a small flame of peace and equanimity in ourselves, we will have already contributed to world peace. Establishing peace in ourselves is the only way we can expect to have the clarity to then express it in our daily lives, in the difficult interactions we have, where peace is sorely needed. Our ability to embody nonviolence and compassion will bring those values more powerfully into the world than any speech we can make.
We have literally hundreds of opportunities every day to make a choice to be loving, to listen and understand others, to give without expecting something. If we can open our hearts to even a few people we encounter, we begin to live as a light for peace, one step at a time. I think there is nothing more important for us to do and nothing more fulfilling.
