Modern science gives us good reason to use sweet fragrances in our spiritual practices. It teaches that the olfactory sense is our most primitive, primal sense and so has the power to connect us to our primordial roots and to trigger and awaken our earliest memories. In that "old" space, healing can take place, particularly healing of the emotional and the spiritual bodies, because in being carried back to the source we are given the opportunity to revisit, confront, work out, and heal any unfinished business, trauma, or pain. That is why the ancient but newly rediscovered practice of aromatherapy has become so popular in modern healing circles.
