I cross the void beyond the mind The empty SPACE that circles TIME I see where others stumble blind To seek a Truth they never find Eternal Wisdom is my guide *I am the Doctor*
Through cosmic waste the TARDIS flies To taste the secret source of Life A presence science can't deny exists Within outside behind The latitude of human minds *I am the Doctor*
My voyage disects the course of TIME WHO knows you say But are you right? WHO search indeed to find the light That glows so darkly in the night? *Toward that point I guide my flight*
As feelers move to end mankind Metallic teeth begin to grind With sword of truth I turn to fight The satanic powers of the night Is your faith before your mind? *Know me, Am I the Doctor?*
