Your mind and body unite when you are truly 100 percent grateful. When this happens, those around you become happier. If you live your life with a heart of gratitude for the blessings heaven has given you, I think you will be able to create even more joy among those around you, and you will be able to spread these blessings to your family, society, nation and world.
