Across the threshold that I dare not shun,
I feel my strength desert me, which of yore
Did pride itself on elevated thought,
And sought the goals of life in time and space.
Once did I reckon it an easy thing
To set the brain in action and to grasp
The nature of reality by thought.
But now, when I would search the fount of life
And comprehend it as in truth it is,
My thought appears as some blunt instrument;
