Although she feeds me bread of bitterness, And sinks into my throat her tiger’s tooth,
Stealing my breath of life, I will confess
I love this cultured hell that tests my youth.
Her vigor flows like tides into my blood,
Giving me strength erect against her hate,
Her bigness sweeps my being like a flood.
Yet, as a rebel fronts a king in state,
I stand within her walls with not a shred
Of terror, malice, not a word of jeer.
Darkly I gaze into the days ahead,
And see her might and granite wonders there,
Beneath the touch of Time’s unerring hand,
Like priceless treasures sinking in the sand
