I think this song is describing the thoughts that flow through the mind of a person when they are on the verge of suicide. He is perhaps thinking about man as a divine, but imperfect being.

Does death come alone or with eager reinforcements?
Does death come alone or with eager reinforcements?
Death is centrifugal
Solar and logical
Decadent and symmetrical
Angels are mathematical
Angels are bestial
Man is the animal
Man is the animal

The blacker the sun
The darker the dawn
Flashes from the axis
Flashes from the axis
On the hummingway to the stars

Holy, holy
Holy, holy
Holy
Oh, holy
Holy, holy
Holy, holy
Holy
Holy, holy
Holy, holy
Holy

Man is the animal

The blacker the suns
The darker the dawn

Fire in the Mind

"Fire in the Mind is a New Mexico mystery story of a different kind. Johnson has given us a thought-provoking look at a fascinating subject." -- Tony Hillerman
