Can it be used to help groups of people or even global crises?

Yes, this is one of the wonderful benefits of Reiki and is why it is such a wonderful technique for the new millennium. It allows individuals and groups to do something positive about the challenging situations we see on the news involving so many people all over the planet. Reiki can be used to reduce suffering and help people any where in the world. See our World Peace Grid Project.
