It is important NOT to leave your circle until it has been uncast, Take your Athame and cut straight down through the air, come back up and go straight down again. Now take and put your hands together infront of you, and move the three circles (saltwater, Incense, sword) apart ( as if your are parting a curtain) walk throughthe circle, turn and facing the circle, close the opening with your hands, This will seal the cirlce so that nothing can enter or leave while you are gone. When you return to the circle follow the same procedure, Cut the circle, open, step through, and close.
( only used when the room has been cast )
After casting a room circle point your wand at the doorway and say:-
" This doorway is a go between allowing us to pass unseen, through it may enter no harm
Disturbing its inner calm
and we may return within "
Everytime you leave/enter trace a pentacle on both sides.
