The poem is about a mind's ascension to higher things because he can 
perceive systems.
And he sees that not just the real world has substance as a system or a universe.
All systems do.
Human politics is a universe.
A computer's programming is a universe.
He sees the kind that he has ascended beyond are trapped in the universes
they have built in their minds and the real world.
They are blind to the reality of the real world.
He is tempted to re-enter the universe of human thought and damage it (in
no supernatural way, just with words and proofs et cetere).
But he then sees that the blind have the potential to also reach beyond like
him; to also know and see universes.
For those who also transcend, he will be their guide. They will be a kind of
their own. The poem ends on that happy note.

The poem is about vision really.
