Odin's Task

What does "an eye for an eye" mean?
Steal away what was lost?
Or is it more than what is seen?
Wisdom at any cost!
Power hungry, I hear them call,
But their vision is truly small.
Power hungry?
Power hungry!
Ha! I ought to conquer them all.

What does "an eye for an eye" mean?
Is it Vengeance perhaps?
A greater sense, one far more keen?
Or wisdom for whom lapse?
I need to know the words I seek.
Scour works, interest at its peak!
I need to know...
I need to know...
That I do not grow ever weak.

What does "an eye for a eye" mean?
Nine days I hungered so
And at nights: thirst. All as to glean
from runes, wisdom through woe,
The primal truth that of this realm
In search of growth I'm at the helm.
The primal truth?
The primal truth...?
May the mead of blood overwhelm!
