Maaroo, First Mehl:

Some call him a ghost; some say that he is a demon. Some call him a mere mortal; O, poor Nanak! ||1||

Crazy Nanak has gone insane, after his Lord, the King. I know of none other than the Lord. ||1||Pause||

He alone is known to be insane, when he goes insane with the Fear of God. He recognizes none other than the One Lord and Master. ||2||

He alone is known to be insane, if he works for the One Lord. Recognizing the Hukam, the Command of his Lord and Master, what other cleverness is there? ||3||

He alone is known to be insane, when he falls in love with his Lord and Master. He sees himself as bad, and all the rest of the world as good. ||4||7||
