Austrian poet Jura Soyfer, dead in a concentration camp

The great Austrian psychiatrist, Viktor E Frankl, quotes in his masterpiece, "The Suffering Man", a verse from the Austrian poet Jura Soyfer, who died in a concentration camp, which I wish to share with you for his striking beauty:

Only way to release
to the man who sleeps in us:
ask ourselves at every moment if man we are
and at every moment answer: No.
The sketch we are poorly devised
of man, still to draw.
A poor curtain for the big scene.
Men call us? Not yet. Wait.
