Question By The Night Ghost

In the old days every person knew that the night ghost could be encountered frequently

This ghost asked a question

If you can solve it you are rescued

If not I'll put you under a spell and you have to die very soon

One night a man was on his ways when the night ghost asked him the question

To whom does the night belong

It does not belong to you nor me

It belongs to him to whom it is vital

And that was answered correctly and the man was free
