This is one of those pages that grows as I gather more information.

I got these from a beautiful site that is no longer online.

Air, Fire, Water, Earth,
Elements of Astral birth,
I call you now; attend to me!
In the circle, rightly cast,
Safe from psychic curse or blast,
I call you now; attend to me!
From cave and desert, sea and hill,
By wand, blade, cup and pentacle,
I call you now; attend to me!
This is my will, so mote it be!
