Scented essences have amazing powers! They contain a part of the universe: the warmth of the Sun, the strength of the Earth, the calmness of the Moon, dew and rain, wind and air!
An essential oil is the basis of the plant in its most concentrated form. When left out in the open, essential oils evaporate into the air like mist. You can recognise a real essential oil when you pour a drop on a paper napkin. After it evaporates, it will not leave any kind of trace.
