If you truly feel you have been magically bound, then here is what you can do...
On the night of the full moon, gather together sage, lavender, and rosemary. Mix together in morter and pestle to create and incense. Also, you will need salt, a candle, and water from a live source be it the sea or a river or spring. Snow is also one of the most pure forms of water next to that of a live source so you can use that if it snows in your area. Cast a circle and call Aradia to you. Tell her what you feel and what you feel. Make it personal. Ask her assistance in the unbinding of you and your sister. If you haven't already lit the incense then do so now. Take it and smudge yourself with it and say something about the element of air removing the bind. I would say .
''the swift wings of the air removes the bind that should not have be done.''
With the fire, be careful, but very quickly touch the flame and say
''the burning heat of the flame charrs, burns and removes the bind that should not have been done.''
purify the water with the salt if you have not done so already. Sprinkle yourself with it and say
The raging current of the water removes the bind that should not have been done!''
Take the salt and sprinkle yourself with it and say
''the incredible strength of the earth removes the bind that was not to be done!''
Stand in the Goddess position and say:
''may the great and mystical all mother remove the bind that was set upon my body, mind, and spirit. Gracious mother Goddess, you who have been with me from my frist breath, please set me free of the bonds that hold me!''
Close your eyes and let the mother do her work. YOu will feel the light as it descends upon your body. When you feel it has left you and the binding has been undone, say So Mote It Be!
Thank the mother Goddess and the elements. Return them all back to the earth. It is done.
