Couldn't think of any title but this ..
In Poetry the couplet does not has a title

. If you are talking about thread title, then it should be Life Forever ...
I don't know, in what context you write this couplet, but if any poet will see this,then definitely he assumes the same meaning as I did.
This couplet bears two meaning.....!!!!!! the one hidden meaning which I assumed and the second in which you wrote this..Nd both are deep.......
انتظارِ موت نے شب بھر جگایا اور پھر
صبح ہوتے زندگی میرے گلے سے آ لگی
Great one
Really a nice one.....!!!!!!!!!!
