If you give your life as a prayer, you intensify the prayer beyond all measure. To attain inner peace you must actually give your life, not just your possessions. When you at last give your life bringing into alignment your beliefs and the way you live, then, and only then, can you begin to find inner peace.
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.
