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.
Peace Pilgrim (1908 - 1981), born Mildred Lisette Norman, was a pacifist, vegetarian, and peace activist. The spiritual classic Steps Toward Inner Peace is a transcript of a 1964 talk she gave on KPFK radio in Los Angeles, California. In that year she completed 25,000 miles on foot for peace and stopped counting miles but continued to walk on her pilgrimage for another 17 years. Her only possessions were the cloths on her back and the few items she carried in the pockets of her blue tunic which read "PEACE PILGRIM" on the front and "25,000 MILES ON FOOT FOR PEACE" on the back. She had no organizational backing, carried no money, and would not even ask for food or shelter. It had to be offered without asking. For 28 years all her needs were met. "Aren't people good," she would often say. She spoke to all who would listen about the entire peace picture; peace among nations, peace among groups, and the very important "inner peace" because she believed that was where peace began.
