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.
The very thoughts that allow us to hurt another limit our ability to express the will of creation through ourselves. At the same time, each time we love another, we have just loved ourselves. Each time we create time for another, strive to understand another, we have just done each of these things for ourselves. When we disapprove of the actions, choices or beliefs of others, we witness through them those portions of ourselves that ask for a greater healing.
