The Chronicle of the Saving Remnant
A well-known Sufi was asked, 'What is invisibility?'
He said: 'I shall answer that when an opportunity for a demonstration of it occurs.'
Some time later that man and the one who had asked him the question were stopped by a band of soldiers.
The soldiers said: 'We have orders to take all dervishes into custody, for the king of this country says that they will not obey his commands, and say things which are not welcome to the tranquility of thought of the populace.'
The Sufi said: 'And so you should, for you must do your duty.'
'But are you not Sufis?' asked the solders.
'Test us,' said the Sufi.
The officer took out a Sufi book. 'What is this?' he said.
The Sufi looked at the title page. 'Something which I will burn in front of you, since you have not already done so,' he said.
He set light to the book, and the soldiers rode away, satisfied.
The Sufi's companion asked: 'What was the purpose of that action?'
'To make us invisible,' said the Sufi, 'for to the man of the world, 'visibility' means that you are looking like something or someone he expects you to resemble. If you look different your true nature becomes invisible to him.'
