Usually we think of relaxing and healing as things that happen when we are alone. But many thousands of people have participated in collective walking meditation and mass sitting meditation in some of the world’s busiest cities. People have walked mindfully and peacefully around the Hoan Kiem Lake in Hanoi. They have left footprints of peace and freedom on the ancient streets and piazzas of Rome. Thousands of us have sat in silence and stillness in London’s busy Trafalgar Square and in Zucotti Park in New York City. Everyone who participates and everyone who witnesses this collective practice has a chance to get in touch with the energy of peace, freedom, healing, and joy. The collective energy generated on such occasions is a gift that we can oer ourselves, one another, the city, and the world.
