Shakespeare's sonnets

If the dull substance of my flesh were thought,
Injurious distance should not stop my way;
For then despite of space I would be brought,
From limits far remote where thou dost stay.

No matter then although my foot did stand
Upon the farthest earth removed from thee;
For nimble thought can jump both sea and land
As soon as think the place where he would be.

But ah! thought kills me that I am not thought,
To leap large lengths of miles when thou art gone,
But that so much of earth and water wrought
I must attend time's leisure with my moan,

Receiving nought by elements so slow
But heavy tears, badges of either's woe
