From Omar Khayyam
Each spot where tulips prank their state
Has drunk the life-blood of the great;
The violets yon field which stain
Are moles of beauties Time hath slain.

Unbar the door, since thou the Opener art,
Show me the forward way, since thou art guide,
I put no faith in pilot or in chart,
Since they are transient, and thou dost abide.
