Lifetime
In a dark sea of centuries wherein nothing seemed to flow, a lifetime was only a brief eddy, even for the man who lived it. There was a tedium of repeated days and repeated seasons; then there were aches and pains, and finally Extreme Unction.
And a moment of blackness at the end – or at the beginning, rather.
For then the small shivering soul who had endured the tedium, endured it badly or well, would find itself in a place of light, find itself absorbed in the burning gaze of infinitely compassionate eyes as it stood before the Just One. It would be hard to believe differently.
Canticle of Leibowitz by Walter Miller
