I got this one from The Wiccan Book of Ceremonies and Rituals by Patricia Telesco, and made a few changes to it. I thought it was very lovely.
Preparations
Gather together as many light sources as possible. Suggestions include white candles, flashlights, incense sticks, and small oil lamps for indoor gatherings. Outdoors, consider torches or a well-tended bonfire.
For the activities in this ritual you will need: some ice or snow; a cauldron or cup of soil and a seed; your personal journal and a pen; ale or buttered toast for an offering; corn husks for decoration; and any white items. This is Brigid’s color as the Maiden aspect of the Goddess.
The Altar
Arrange your light sources in a pleasing manner around the ritual space, but leave them dark. The center of the altar holds a coal or other fire source from your hearth. It is the only thing burning at the start of the ritual. Next to the fire source, leave a container of ice or snow. On the other side place your seed, and dish.
Corn husks are scattered on the surface of the altar like a cloth. Your personal journal and pen sit at one corner. The offering of toasted bread or ale rests on the other corner.
Invocations
Before starting the invocation, go to your door and open it, saying:
“Brigid, I welcome You to my sacred space.
As You enter, bring with You the fires of warmth and fertility.”
Traditions similar to this are very old, the opening of the door symbolically making way for the powers of light.
Go to the center and pick up the sacred fire. As you walk the circle reciting the invocation, begin igniting the light sources in that quarter of the room. The creates the visual effect of the circle magic coming alive around you.
East
I welcome the Air, the rising sun.
Let the light-filled wind bring inspiration
and the breeze of new beginnings.
South
I welcome the Fire, and the noonday sun.
Let the purifying light of the Spring bring energy
and courage with which to walk my path daily.
West
I welcome the Water, and the setting sun.
Let the twilight bring thoughtfulness
and wisdom to my magic.
North
I welcome the Earth, and the resting sun.
Let the moment of fertile darkness give my soul peace,
and my magic foundations.
Center
I Welcome the Spirit of ever-burning truth and light.
Let your fires be ever present in my mind, my heart, and my magic.
Meditation and Visualization
Sit in the center of the light generated around the room. Look at the flame of the sacred fire until you can see it in your mind’s eye clearly. Close your eyes and breathe deeply, continuing to visualize that flame. See it slowly growing in power and beauty until the fire encompasses your whole being, restoring strength, health and insight.
Once you feel the energy of that light filling you to overflowing, shift your awareness. See yourself as you sit right now, with light shining all around you. Slowly shrink that light down into one brilliant spark that resides in your heart chakra, banishing any shadows that hide within. This ember of the Spirit, this light of truth is always with you, empowering and guiding your magic.
Sit quietly pondering the significance of the light in your magic and everyday life, and – when you feel ready – open your eyes and make note of any insights in your journal. Then continue with the ritual.
The Ritual
Stand in one place, raise your hands toward the sacred altar, close your eyes, and whisper this chant three times:
The Goddess in me, in my heart.
The Goddess in me, in my spirit.
The light in me, in my body.
The light in me, in my mind.
The light in me, in my soul.
Put your arms down, open your eyes and say:
I welcome the Light.
Walk up to the altar now and, taking the container of soil and seed in hand, raise it to the heavens.
This soil of Earth is also the soil of my spirit.
Today, I plant the seed of (fill in with a quality that you wish to
develop)
in this loam to be warmed by the returning sun, and grown with love.
Plant the seed in the soil, and put the container in front of you on the altar.
Take the container of partially melted snow or ice and raise it upward, saying:
This is the Water of the Maiden who returns to Earth today,
generating life and fertility with Her warmth.
Pour the melted snow into the container with the soil and seed.
This Water shall likewise nourish the seed of now growing in my soul.
Pour the remaining liquid out to Earth as a libation. If the ritual takes place indoors, save the snow or ice until the circle is closed, then take it outside. After the ritual, the soil and seed should be transferred to a large pot and placed in a sunny window to activate the magic.
Even in ancient days this festival included a time for observations, specifically to figure out the weather to come. That’s how Groundhog’s Day got started. So consider taking a walk outside to see what signs you can discern from Nature’s storehouse of wisdom.
A great activity for kids is making their own Imbolc candles. All you need for this is melted wax, a wick, and an old milk carton that acts as a mold. Allow the kids to add any powdered herbs or aromatic oils they wish, then keep this safely stored away for next year’s festivities.
Closing the Circle
North
Under the moonlight the resting Earth
lay until the dawn brings a new birth.
West
The Waters recede with a setting sun,
but the magic continues when the circle is done.
South
The fires die down, the candles go out,
but within my heart there lingers no doubts.
East
The Air calms, but the breath of Spirit remains.
Merry part, and Merry Meet again!
Instead of dismissing the center point, go to your door again, taking with you the toasted bread. Toss the bread out the door for the birds, saying:
Accept this gift of bread to nourish the children of the
winds as my thanks to
You, Brigid, for Your presence…
for sharing the fire from Your hearth to bless, inspire and heal me.
May I keep these embers safely burning in my heart.
Close the door.
So mote it be!
