The Aromatherapy of the Soul is based on traditional aromatherapy and expands it with a new shamanic-psychological dimension. This approach focuses on the subtle relationship between the essence of the plant and the essence of the human being. Each plant species possesses a unique essence that resonates with the human essence. This means that whether we like or dislike a plant's vibration, we can learn a lot about ourselves through the characteristics of the incense or scent. We can also use this information for healing by receiving healing impulses from the plant. The system of this new aromatherapy is based on nine scent gates, "sacred ideas," that represent our inner life. Passing through such a scent gate grants an initiation into the respective spiritual realm: There is the Gate of Er.
