How can the world be here,yet he is not?

How can the world be here,yet he is not
But in that other  country  he must dwell
Is that heaven or some unused old lot?
How can the world be here,yet he is not?
Can it be his wife he has forgot?
He left me lone, a bird caught in a net
What truth is there and which of us can tell?
How can the world be here,yet he is not?
In  that other country  now he dwells.
