The World of Time, by Rumi

Every instant thou art dying and returning.  "This world is but a
     moment," said the Prophet.
Our thought is an arrow shot by Him: how should it stay in the air?
     It flies back to God.
Every instant the world is being renewed, and we unaware of its
     perpetual change.
Life is ever pouring in afresh, though in the body it has the
     semblance of continuity.  
From its swiftness it appears continuous, like the spark thou whirlest
     with thy hand.
Time and duration are phenomena produced by the rapidity of Divine
     Action,
As a firebrand dexterously whirled presents the appearance of a long
     line of fire.

("The World of Time", translated by R.A. Nicholson, Rumi, printed 2006)
