May the LORD bless you, and keep you;
   May the LORD make his face to shine upon you, and be gracious to you;
   May the LORD turn his countenance to you and grant you peace.
The Priestly Blessing is set forth at Numbers 6:24-26

Meal Blessing and thanks

For the seeds that grew them,
For the cows that gave the milk,
For the chickens that laid the eggs,
For the lives of the animals whose bodies will nourish ours,
For those who planted and tended,
For the wind, the sun, the rain, and the earth that nourished them,
For those who harvested, milked, gathered, and slaughtered, for those who carried, prepared and delivered,
I thank you Lord and Lady.

A Blessing For Food
by Geoffrey Cohen
Thank you food for sacrificing yourself for me.
For your death provides me with life.
Your energy becomes my energy,
and I become you.
So I pray to you to share with me what gifts you can,
and I thank you and honor you.

Blessed Be!.

Computer Blessing
Zhahai Stewart

   Blessings on this fine machine,
   May its data all be clean.
   Let the files stay where they're put,
   Away from disk drives keep all soot.
   From its screen shall come no whines,
   Let in no spikes on power lines.
   As oaks were sacred to the Druids,
   Let not the keyboard suffer fluids.
   Disk Full shall be nor more than rarity,
   The memory shall not miss its parity.
   From the modem shall come wonders,
   Without line noise making blunders.
   May it never catch a virus,
   And all its software stay desirous.
   Oh let the printer never jam,
   And turn my output into spam.
   I ask of Eris, noble queen,
   Keep Murphy far from this machine.

These are so good.
(I bless my food, and the source.  Even when I go fishing, I thank the fish for giving itself to me.)
these made me sigh...
