Cascarilla is powdered egg shell. The shells are so finely ground that it feels as soft as baby powder. When removed from the cup, it maintains it's form and can be used as one would use a soft piece of chalk. Or, if mixed with water, you will find that the soft-chalk dissolves easily.~ Cascarilla repels negative energy, and the vibration of negative energy. Different uses: 1. Purification baths. 2. As a piece of chalk to draw sigils, and circles of protection for Magickal rituals. 3. This is great to have if you are going to meditate, astral project or perform visualizations. You can use it as a powder and "dust" yourself with it or you can use it as a chalk and make the sign of the cross on different areas of your body (back of neck, forehead, temples, hands, chest and bottom of feet). 4. If you have psychic abilities (Mediumship, Empathic, Clairsentient, Clairvoyant, etc), you can dust yourself or make the sign of the cross as previously mentioned, and it protects you from psychic attack and "energy vampires." Cascarilla also keeps away negative spirits. 5. Cascarilla also keeps away non-corporeal beings (spirits, ghosts, demons, etc). If you feel like your home may be haunted, this would be a good repellent (after a thorough house cleansing!!). Be warned, if you have spirits around that you like talking to, you may find it more difficult to communicate with them! Cascarilla does not discriminate between good and evil-it just provides a barrier between the physical and spiritual world.
