A note on simplicity:
When we try to over complicate things, we can often end up not having time to fit it in or we put it off because it is so involved. The mind may engage and think 'Is this right/wrong?' or 'Did I miss a section?' Maybe we do it once and move on to the next thing and then the next. I like simple and I find it works. Simple rituals or practices carried out with a strong intention and focus reap many treasures. Keep it simple, but persist and keep doing it.
A simple fire ceremony can be carried out using a candle or in the hearth of your living room. You don't have to be limited by your circumstances, get creative and find different ways of doing it that are practical to the time of your need.
If you have outdoor space you may wish to create something larger however. You can style it to suit your needs and means, each time it may be different. Experiment!
I have a portable fire bowl that I carry to different places with me. I especially love going to the beach and having a fire on the new or full moon. The beauty of the fire bowl is that you aren't scorching the earth or leaving any debris.
Fire has a consciousness and likes to be fed, it transmutes often with great relish. You can feed the fire with old outdated thoughts and patterns that need to be released. You can let go of the burdens you are carrying and may be carrying for your ancestors.
To begin, write down what you wish to let go of on a piece of paper. You can write this as a letter to the fire, begin by thanking the fire for taking from you and transmuting that with no longer serves you. Then writing down what you are letting go of, going in to as much detail as you wish to. Let it out! Go in to automatic writing and release it all.
Make a talisman that you create with intention, letting go of the energy from your body and mind as you make it. Collect natural items from nature that are combustible and non-toxic, items that can burn easily.
When you are ready, open with an invocation, speak to your spirit guides, or Existence, whatever or whomever you are comfortable with and fits in with your cosmology. Thank them for being with you and witnessing your release, for supporting you and holding the container for you to do your sacred work.
Next, when you are ready, let go, feed the fire with your paper letter or talisman. Thank the fire as you do so, for taking and transforming that which no longer serves you.
When you feel complete, close by thanking your guides and releasing them, knowing you have been heard.
Feed something to the fire in gratitude. Corn, herbs, a twig or log would be perfect gifts. If you are using a candle flame for your ceremony, burning a single leaf of herb will suffice.
As you continue to be with the fire, look out for any omens and signs that the fire may offer to you. As the fire slows down and only embers remain, it is a wonderful thing to do to gaze in to the embers divining information that may be offered.
Another intention you can do fire ceremony with, is to empower your dreams. Instead of feeding what you wish to release, you may feed your dreams to the fire. Imbuing your talisman with what you wish to create in your life, for your community and for the world.
You can also write this down and feed the letter to the fire, or a combination of both written word and talisman. As you offer your dreams, know they are being heard.
