Everything in the world and in the Universe is all made up of energy. Humans, specifically, have energy centers, the chakras, that connect them with their subtle energy bodies (ie the Root chakra connects us with the etheric body). Keeping these vibrating high leads to a fulfilled and balanced life. One can do so through many ways including exercise and eating healthy, but the best way is using natural methods like aromatherapy. The most powerful method, however, is meditation.
