A man who had spent many years trying to puzzle out meanings went to see a Sufi and told him about his search.

The Sufi said, 'Go away and ponder this –IHMN
The man went away. When he came back, the Sufi was dead.

'Now I shall never know the truth!' moaned the puzzler.

At that the moment the Sufi's chief disciple appeared. '

If,' he said, 'you are worrying about the secret meaning of IHMN, I will tell you. It is the initials of the Persian phrase 'In Huruf Maani Nadarad' – which means, 'These letters have no meaning.''
