Fire can release a spell, charm, or wish into the cosmos, where it'll begin to work. For this spell you'll need to build a small safe fire. You may use a fireplace, cauldron, or other heatproof container. All you'll need are a few twigs. Once the fire is burning, don't leave it unattended. Before you build your fire, write your charm on a piece of paper.

When the fire is burning, speak these words into it:

Fire, for centuries we've tended your flame,
And our partner in magic you remain.
I now have a wish, a request.
I ask that my need be blessed.
Upon this paper I've written a charm.
May it come to me without harm.
Into your sacred flame this charm I cast,
Send me my wish, let it come to pass.

As the charm burns, don't look away. Watch as the smoke carries your wish to the Divine. Watch the fire as it burns out. When the ashes are completely cool, discard them in the trash or compost.
