The perfume essential oil roller enhances balance of the body, mind and soul. The Dara Celtic Knot is a Celtic symbol for inner strength. The symbol comes from the Gaelic word ‘Doire’, which means ‘Oak Tree’. The Dara Knot is believed to represent the magnificent root system that robustly holds up the heavy body of an ancient oak. The Celts revered trees and believed oak trees to be sacred. One of the most central aspects of the knot is the never ending lines representing love and eternity. Each loop of the knot is used to illustrate how an individual is interwoven into all aspects of life.
