Walking mindfully on the Earth can restore our peace and harmony, and it can restore the Earth's peace and harmony as well. We are children of the Earth. We rely on her for our happiness, and she relies on us also. When we practice walking meditation beautifully, we massage the Earth with our feet and plant seeds of joy and happiness with each step.
Peace is a day-to-day problem, the product of a multitude of events and judgements. Peace is not an 'is' it is a 'becoming.'
