Quest for Knowledge lyrics

I know that I hung On the wind swept tree Swung there for nine long nights Gashed with a blade Bloodied for Odin Myself an offering to myself Knotted to that tree No man knows Wither the roots of it run None gave me bread None gave me drink Down to the deepest depths I peered To snatch up the runes With a roaring scream I fell in a dizzied swoon Well being I won and wisdom too I grew and joyed in my growth From a word to a word From a deed to another deed
