This Marriage - Ode 2667 by Rumi

May these vows and this marriage be blessed.
May it be sweet milk,
this marriage, like wine and halvah.
May this marriage offer fruit and shade
like the date palm.
May this marriage be full of laughter,
our every day a day in paradise.
May this marriage be a sign of compassion,
a seal of happiness here and hereafter.
May this marriage have a fair face and a good name,
an omen as welcome
as the moon in a clear blue sky.
I am out of words to describe
how spirit mingles in this marriage.

known as the "Apache Wedding Blessing) (it isn't Apache, but a nice poem)

May the sun bring you new energies by day;
May the moon softly restore you by night.
May the rain wash away any worries you may have
And the breeze blow new strength into your being.
And all the days of your life,
May you walk gently through the world And know its beauty.

Now you will feel not the rain, for each will shelter the other.
Now you will feel not cold, for each will warm the other.
Now you will feel not solitude, for each will company the other.
Now you are two persons, but both will lead one life.
When you go to your dwelling to enter into the days of your life,
May happiness be your companion, and together
May your days be good and long upon the earth.

Please join us in a prayer to offer loving kindness:

May all beings be happy, content, and fulfilled.
May all beings be healed and whole.
May all have whatever they want and need.
May all be protected from harm, and free from fear.
May all beings enjoy inner peace and ease.
May all beings be awakened, liberated, and free.
May there be peace in this world, and throughout the entire universe.

"Blessing for a Marriage" - James Dillet Freeman 

May your marriage bring you all the exquisite excitements a marriage should bring, and may life grant you also patience, tolerance, and understanding. May you always need one another — not so much to fill your emptiness as to help you to know your fullness. A mountain needs a valley to be complete. The valley does not make the mountain less, but more. And the valley is more a valley because it has a mountain towering over it. So let it be with you and you. 

May you need one another, but not out of weakness. 
May you want one another, but not out of lack. 
May you entice one another, but not compel one another. 
May you embrace one another, but not out encircle one another. 
May you succeed in all-important ways with one another, and not fail in the little graces. 
May you look for things to praise, often say, “I love you!” and take no notice of small faults.
If you have quarrels that push you apart, may both of you hope to have good sense enough to take the first step back. May you enter into the mystery that is the awareness of one another’s presence — no more physical than spiritual, warm and near when you are side by side, and warm and near when you are in separate rooms or even distant cities.
May you have happiness, and may you find it making one another happy.
May you have love, and may you find it loving one another.

Blessing for Wedding - Jane Hirshfield

Today when persimmons ripen
Today when fox-kits come out of their den into snow
Today when the spotted egg releases its wren song
Today when the maple sets down its red leaves
Today when windows keep their promise to open
Today when fire keeps its promise to warm
Today when someone you love has died
or someone you never met has died
Today when someone you love has been born
or someone you will not meet has been born
Today when rain leaps to the waiting of roots in their dryness
Today when starlight bends to the roofs of the hungry and tired
Today when someone sits long inside his last sorrow
Today when someone steps into the heat of her first embrace
Today, let this light bless you
With these friends let it bless you
With snow-scent and lavender bless you
Let the vow of this day keep itself wildly and wholly
Spoken and silent, surprise you inside your ears
Sleeping and waking, unfold itself inside your eyes
Let its fierceness and tenderness hold you
Let its vastness be undisguised in all your days
