Inner stillness is perhaps our greatest ally. Gandhi once wrote that silence brings "the highest potency and is self-acting power." Prayer, meditation, reading scripture (which is, to me, alive with silence, embedded with sacred codes about our deepest mind) -- even quiet walks -- become healing acts. These quiet the world's noises and provide clues about who we are and our healthiest directions.
As a witness for Peace, our role was to witness in two senses of the word: we SAW, and by our presence we offered affirmation by word or example of a solidarity based on love and faith and the Good News. The word that is much used is "accompaniment." Our contribution was less in our doing than our being-with.
