This is a generic solitary ritual template for Celtic rituals, adapted from a group ritual template. It's also available as a Word/RTF document with the chants filled in. Please note that while I frequently offer alcohol, you are free to substitute something else if you like.

Preparation

The participant gathers the following offerings (vegetable oil may be substituted if necessary):

The participant also fills the Well with fresh water and places the blessing cup and branch next to it. If necessary, s/he places an offering bowl on the altar as well. He/she then clothes in ritual garb and performs a brief pre-ritual meditation to quiet the mind.

Gathering

Participant gathers at the ritual area and sounds a musical signal (such as a chime) three times, then says:

I am here to honor the gods.

Honoring the Earth Mother

Áine Chliar, daughter of Manannan, woman of the hills and land...
Great Earth Mother, my life is nursed from your bounty.
You are the food that nourishes me, the wealth that enriches me, even the very ground I walk on.
O bright goddess, all joy and prosperity comes from you, and it is you who sustains me.
Áine, I honor you now to thank you for the bounty you bestow upon me.

(Áine Chliar is pronounced "awnyeh cleer")

P makes an offering and says:

Earth Mother, accept my sacrifice.

Participant sings Blossom Lifter 1x

Bardic Inspiration

P calls to Brighid asking for the gift of poetic inspiration:

Bright Brighid, Daughter of the Dagda, Flame of Inspiration,
Maker of metal, Maker of good health, Maker of song,
With you as my mother I need fear no sickness,
With you as my mother I need fear no dull swords,
With you as my mother I need fear no empty words.
I am triple-blessed, O shining light of the hearth,
and I your child ask you to alight in my heart,
Alight in my head, and alight in my voice,
That I may give praise to the powers with good skill.

Outdwellers

P pours a cup for the Outdwellers and takes it out of the ritual space, then says:

You who come from the outer dark,
You who stood against the gods and man,
You who are cold of heart and cruel of mind,
Take this and trouble not my work.

Establishing the Sacred Grove through Fire, Well, and Tree

Sacred Fire

Participant says:

I kindle the sacred fire,
Claiming this land and time for my own.
The shape-fire burns bright,
This is the center of the world,
My Meath, Tara, and Uisnech.
Let none stand against me,
Let the world turn around me,
Let me have a good fire,
As I call the Kindred forth.

(Meath is pronounced mathe with a soft th; Tara is tah-rah; Uisnech is ish-nuck)

P lights the sacred fire and places incense into it to hallow the space, then says:

I kindle the sacred fire in wisdom, love, and power. Sacred fire, burn within me.

Sacred Well

Participant says:

I silver the sacred well,
From which five rivers of wisdom run,
Salmon swimming, hazel hanging high.
Bubbling brightly Segais, source of the Boyne,
This is the center of the world.
Let none stand against me,
Let the world turn around me,
Let the well be deep with wisdom,
As I call the Kindred forth.

(Segais is pronounced sheh-gaish; Boyne is pronounced boin)

In the depths flow the waters of wisdom. Sacred waters, flow within me.

Sacred Tree

Towering high, hanging heavy with hazel,
Strength of Taranis, the thunder and wheel,
From Tara to nemeton, star-reaching bile,
This is the center of the world.
Let none stand against me,
Let the world turn around me,
Let the tree be tall and strong,
As I call the Kindred forth.

P dresses and censes the bile, then says:

From the depths to the heights spans the world tree. Sacred tree, grow within me.

Opening the Gates Between the Worlds

P prepares an offering for the gatekeeper and says:

Oh Manannan, powerful son of the sea, holder of the magics of the crane bag, I ask that you hear my call. Oh Lord of the Otherworld, bearer of the silvered apple branch, join with me this day, so that you may guide me in my workings. Mist-shrouded rider of the maned waves, accept my offering and open the gates between my realm and yours.

You who brought the Lia Fal and cast out the Fir Bolg and Fomoire,
