Here is a part in the book "The Power is Within You" by Louise L. Hay that I love -
"Every time you use your consciousness in a positive way, you are connecting with other people who are doing the same. Every time you use it in a negative way, you are also connecting to that. Every time you meditate, you are connecting with other people on the planet who are meditating. Every time you visualize good for yourself, you do it for others as well. Every time you visualize the healing of your body, you connect with others who are doing the same thing. Our goals are to expand our thinking and to go beyond what was, to what might be. Our consciousness can create miracles in the world."
