How to do A Cone Of Protection
Sit in a protected circle. Close your eyes and begin to meditate on building a cone of energy around you.
Visualize an electric blue light building around the room that begins to swirl like a vortex. It is moving towards you. When it engulfs you it begins to turn white, then a gelatinous silver.
It surrounds you and will be there to reflect any negative energy or thought forms that come your way.
If you are new to Magic you may need to renew this mirror 2-3 times a day until your power builds.
