If that high world, which lies beyond
Our own, surviving Love endears;
If there the cherish'd heart be fond,
The eye the same, except in tears -
How welcome those untrodden spheres!
How sweet this very your to die!
To soar from earth and find all fears
Lost in thy light - Eternity!

It must be so: 'tis not for self
That we so tremble on the brink;
And striving to o'erleap the gulf,
Yet cling to Being's severing link.
Oh! in that future let us think
To hold each heart the heart that shares;
With them the immortal waters drink,
And soul in soul grow deathless theirs

George Gordon Byron
