The Roll On has the same effect as the Aura Spray. It is easy to take with you and to always have it to hand. Roll it on your left wrist. Then rub your two wrists together so you will have the oil on both wrists. The oil will be effective and will influence your energy field.
Do you find that you are suddenly tired, down or ill for no reason, then this can be a signal that you are suddenly empty (for example from negative impulses, thoughts, emotions or connections). The Roll-On helps you to immediately reset to your own energy.
