To cast, simply recite the spell with the full weight of your energy & intention behind the effort.  You can recite out loud, or through telepathy (your mind).

If you feel you need candles or other draws like incense or stones please use them if they make you feel in the appropriate state of mind.

Or if you'd like to bind the energies of the spell to a stone for boosting purposes use these instructions with a candle:
Pass the rock over the flame three times after the spell is recited.
Keep the rock near you to have the spell surround you.
You can use the spell as much as you like!

Communion with Spirits

Wake the passed spirit!

Show yourself to me!

Shake the bones of rattling corpses

Open thine eyes of spirit be!

Round the realm of forgotten morrows

Through the depths of pass

Light the abyss of greater purpose

Here to me come at last!

(Speak the name of the spirit you are trying to contact – full name is best if known otherwise speak the part of the name you know and try to mention a relative of the person, a place known to them, etc. to ensure you call the proper spirit).
