Plants receive light from the heavens and photosynthesize it, and then it miraculously turns into scent. This invisible aroma is the essence, the spirit of the plant - and it has the power to heal and awaken us in ways our ancestors always knew, and in ways we can come to utilize daily. Whether it comes in incense or oil form, the entheogenic properties of aroma act as a gateway to the divine. This is why scent is almost always a component in ritual and ceremony. It has been proven that scent has a direct effect on our limbic brain, and can impact our emotional state on a very primal level. I also believe it has an effect on our subtle bodies. This is because each essential oil has a different vibration that resonates with different emotions, chakras, organs, body systems, and states of consciousness.
