i nio varldar styr.
Pa Gjallarbron, i alven Gjoll
de doda soker Dig.
O stora gudinna i Hel,
Dit skote ar moder till tiden
hos Dig tager doden sin del.
vart ode styra de
Till Gnipahalan gar var fard
likt Balder da vi do.
hos Doden vi finna vart guld,
nar Balder en gang kommer ater
fran Urtid, Verdandi och Skuld.
da stiger solen upp
nu aterfodd ur vinterns djup
tillsammans med hoder.
nar Balder blev dodad med list.
och alla forsvann ner till Helheim
med Misteltens magiska kvist.
och guden stiger upp
nu aterfodd ur vinterns djup
med solen som sitt svard.
bedriver bed livet sitt spel.
Ditt skote ar moder till tiden
O stora gudinna i Hel!

Translation:
HELHEIM
Heldrasil, oh Heldrasil
The godess Hel shrouded in mist rules in nine worlds On Gjallarbron, in the river Gjöll the dead seek you
Far too many before you despair Oh great godess in Hel Your lap is the mother of time With you death takes it's part
See the Weird Sisters spinning our thread Our fate they rule To Gnipahalan our journey goes Like Balder then we die
We shall travel to Helheim like Hermod did At death we find our gold When Balder once again returns from Urtid, Verdandi and Skuld
When Helgrinden shall open up the sun rises Now reborn from the depth of winter together with Höder
Like a shadow was Loke with Höder when Balder was killed with cunning And everybody disappeared down to Helheim with Mistelten's magical twig
See Helgrinden which opens up and the god arises Now reborn from the depth of winter with the sun as it's sword
The hidden godess in Helheim runs a game with her life Your lap is the mother of time Oh great godess in Hel!

Text from booklet:
"Hel, the goddess of death is also the goddess of fulfillment. Her name means both 'hole' and 'whole' and she governs not only death but also the process of birth and rebirth. Hel was hurled down to the world of ice in the beginning of time there she created nine dark worlds. The bright god Balder and the power of the sun descend into her misty realm, but in the future Balder will be reborn and rise from the womb of Hel like the sun in the springtime."

I don't speak Swedish, but I think it's about the Norse myth where Loki tricks Hod into killing Baldur.
