Lavender is perhaps one of the best oils to use for purification, protection and for healing rituals. It calms and centres the mind and is a great aid for meditation. Its superior balancing qualities are ideal for chakra-balancing. It can be used to seal a platonic friendship, especially between teacher and student. Lavender is a plant of Mercury, and is well suited to calm an overactive mind and to stabilise emotions. It may be used for studying, as it may deepen understanding, but should be avoided in case of mental exhaustion (it will send you to sleep).
