Hope is a state of mind, not of the world. Either we have hope within or we don't; it is a dimension of the soul not essentially dependent on some particular observation of the world or estimate of the situation. It is an orientation of the spirit, an orientation of the heart; it transcends the world that is immediately experienced and is anchored somewhere beyond its horizons.
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.
