Exactly ‘what’

This road to horizon is a long run,
I often wonder where it goes,
Dutifully rises and sets the sun,
Where’s the Destiny – no one knows

A ship that sails in the boundless sea,
No shore,no life just a void to see,
A leave hustled in the wind and dust,
On an unknown journey by the thrust

Flying high to touch the sky,
But its unreachable – however you try,
In the water the reflection won’t stay,
Soon the ripples will fade it away

The falling raindrops can’t quench the thirst,
So envied is now the parched land,
Doesn’t affright that cloudburst,
Worse than it I can stand

A lot of such moments come,
But the words themselves are lonesome,
The heart wants to say a lot,
But clueless as to exactly ‘what’
