Witchcraft and Paganism contains a wide variety of ceremonies, rituals and events celebrating the change of seasons, our lives and specific personal rituals. Within these rites and rituals we use certain tools including candles, incense, talismans, herbs and of course, oils. All these tools posses symbolic aspects that enhance the rite/ritual and desired results the person is seeking in the ritual. Spiritual oils like these are associated with the hidden 5th element of Spirit and help us to reach the unseen, summon from it and speak with the old God's to further our practice.
I use jojoba oil as the carrier oil for all of these.
