Although the Circle is now cast, you are still not ready to start spellwork, rituals or magick. Even though the Guardian (or Watchtower) symbols are in place, it is still necessary to invite the Guardians themselves to join the ritual. This is usually called "calling the Guardians". The reasons for this are twofold. Firstly, the Guiardians will lend the qualities or properties of their respective Elements to the Circle. And secondly, they will "stand guard" over the Circle, watching and waiting, ready to prevent negative energy from entering and interfering. Hence their name - Watchtower Guardians.

In order to call the Quarters, start at the East with your wand and point its tip due East up into the air and say:

Come to us now, O winds of the East
Whirl and swirl 'til the magick has ceased.
Blow through our hearts, and energy raise,
Blow away clouds, blow away haze.
The Circle is open, your power please lend,
Your presence is welcomed - we bid you come in.

Draw an invoking pentagram in the air with the wand. Visualize the Circle filling with a yellow light. Kiss your wand and proceed to the Southern Quarter and again call the Guardians in the same way but this time saying:

Come to us now, O Southerly fires.
Pure strength and warm light - add flames to desires.
Cleanse and purify all that's mundane.
Protect this Circle with pure light and flame.
The Circle is open, your power please lend,
Your presence is welcomed - we bid you come in.

Again, draw an invoking pentagram in the air with the wand. Visualize the Circle filling with a red light. Kiss your wand and proceed to the Western Quarter and again call the Guardians in the same way but this time saying:

Come to us now, O waters of the Western port.
Tides rise and fall, all harm abort.
Wash away troubles, rinse away pain.
W ash over our spirits with oceans and rain.
The Circle is open, your power please lend,
Your presence is welcomed - we bid you come in.

Once again draw an invoking pentagram in the air with the wand. Visualize the Circle filling with a blue light. Kiss your wand and proceed to the Northern Quarter and again call the Guardians saying:

Come earthen power, come from the North.
Lend your strength, lend your support.
As your soil is fertile, this Circle shall be
Nourish all works, as you nourish the tree.
The Circle is open, your power please lend,
Your presence is welcomed - we bid you come in.

You have now called the Quarters and are ready to invoke the Lord and Lady.
