This is the title of an excellent book by Louise Hay. “Be mindful of your thoughts, for your thoughts determine your reality,” says a Jedi Master from the movie Star Wars. There is great wisdom in this statement. It is entirely possible to heal ourselves, starting with our attitudes and mindset. Another author, Dr. Bruce Lipton, suggests that cells have intelligence and act corresponding to the signals received from our thoughts. Dr. Lipton is doing extensive research to provide scientific data to support this idea. It really matters what we think, maybe to an even greater degree than we know.
