Magic is very much real, though it is nothing like what has been depicted in television and movies. Magic, in essence, is energy. Magic is the energy within nature and the natural world. We tap into this energy or impress our wills upon it to send our desires out into the universe with the intent of bringing about a desired change. Magic can be used to help you reach realistic goals or to get closer to nature and your higher, spiritual self.
All that being said, magic is ruled by scientific law. Meaning, if you can't do it with science or other natural means, then you can't do it with magic either. Magic can't be used to reach unimaginable odds or unrealistic goals.
