Analysis of The House Of Dust: Part 04: 07: The sun goes down in a cold pale flare of light

The sun goes down in a cold pale flare of light.
The trees grow dark: the shadows lean to the east:
And lights wink out through the windows, one by one.
A clamor of frosty sirens mourns at the night.
Pale slate-grey clouds whirl up from the sunken sun.

And the wandering one, the inquisitive dreamer of dreams,
The eternal asker of answers, stands in the street,
And lifts his palms for the first cold ghost of rain.
The purple lights leap down the hill before him.
The gorgeous night has begun again.

'I will ask them all, I will ask them all their dreams,
I will hold my light above them and seek their faces,
I will hear them whisper, invisible in their veins. . . . '
The eternal asker of answers becomes as the darkness,
Or as a wind blown over a myriad forest,
Or as the numberless voices of long-drawn rains.

We hear him and take him among us like a wind of music,
Like the ghost of a music we have somewhere heard;
We crowd through the streets in a dazzle of pallid lamplight,
We pour in a sinister mass, we ascend a stair,
With laughter and cry, with word upon murmured word,
We flow, we descend, we turn. . . . and the eternal dreamer
Moves on among us like light, like evening air . . .

Good night! good night! good night! we go our ways,
The rain runs over the pavement before our feet,
The cold rain falls, the rain sings.
We walk, we run, we ride.  We turn our faces
To what the eternal evening brings.

Our hands are hot and raw with the stones we have laid,
We have built a tower of stone high into the sky.
We have built a city of towers.
Our hands are light, they are singing with emptiness.
Our souls are light.  They have shaken a burden of hours. . . .
What did we build it for?  Was it all a dream? . . .
Ghostly above us in lamplight the towers gleam . . .
And after a while they will fall to dust and rain;
Or else we will tear them down with impatient hands;
And hew rock out of the earth, and build them again.
