Protection work in witchcraft is as essential as breathing. We protect our homes, our loved ones, and ourselves on a regular basis.
When you are working with powers which are not well understood, and with other people (either magical or mundane), you can open yourself up to all sorts of negativity.
Protection work includes: Spiritual Bathing, candle work, wearing protection talisman, offerings to your deity for protection, spell casting and rituals e.g. creating sigils, programming servitors, uncrossing work etc; rituals in your home and office to stop jealousy and gossip etc.
