I call upon the internets!

I am looking for a piece of music, a song that I sang back in elementary school chorus. I can remember practically the whole thing, but I'm dying to have a copy of the sheet music. The chorus goes something like this:

May your days and nights be a feast of lights
the eternal flame may it glow in you
and the holy one may he know in you only love.
May the light of peace shine and never cease
and the glow of wisdom illume in you
May you never hate, though it's human to
May you know love.

Google only turns up queries just like this one. Can anybody out there help?
