The disruption of peace, like the flowering of peace begins with the seeds planted within. The following quote comes from an essay, The Root of War is Fear, written by the late Father Thomas Merton.
"Instead of loving what you think is peace, love other men and love God above all. And instead of hating the people you think are warmakers, hate the appetites of the disorder in your own soul, which are the causes of war. If you love peace then hate injustice, hate tyranny, hate greed — but hate these things in yourself not in another." - Thomas Merton, "New Seeds of Contemplation."
