One thing I read is that Khayyam was quoted in Martin Luther King Jr’s speech:
Why I oppose the war in Vietnam. "It is time for all people of conscience to call upon America to come back home. Come home America. Omar Khayyám is right 'The moving finger writes; and having writ, moves on.'" Yeah life must go on and on.
Khayyam always talked about life with a beautiful style. Below is pieces from his Rubaiyyat (quatrains), talking about Life itself.
And, as the Cock crew, those who stood before
The Tavern shouted - "Open then the Door!
You know how little time we have to stay,
And once departed, may return no more."
Oh, come with old Khayyam, and leave the Wise
To talk; one thing is certain, that Life flies;
One thing is certain, and the Rest is Lies;
The Flower that once has blown for ever dies.
Myself when young did eagerly frequent
Doctor and Saint, and heard great Argument
About it and about: but evermore
Came out of the same Door as I went.
With them the Seed of Wisdom did I sow,
And with my own hand labour'd it to grow:
And this was all the Harvest that I reap'd -
"I came like Water, and like Wind I go."
I confess, his words above are moving and make me impressed. Iran has really its jewel.
