RELEASING THE CIRCLE
Once the rite is ended, face North, hold aloft the wand and say:
Farewell, Spirit of the North Stone.
I give thanks for your presence here.
Go in power.
Repeat this same formula to the East, South and West, substituting the proper 
direction in the words. Then return to the North and hold the wand aloft for a 
few moments.
Lay the wand on the altar. Take up the athame.  Standing in the North, pierce 
the circle's wall with the blade at waist level. Move clockwise around the 
circle, visualizing it's power being sucked back into the athame. Literally pull 
it back into the blade and handle. Sense  the circle dissolving, shrinking; the 
outside world slowly regaining its dominance in the area.  When you arrive at 
the North again, the circle is no more.
