Nawab Khadim Hasan was once approached for initiation. He asked the visitor if he would like a murshid who was a leaf, a stone or a log? The visitor was quite surprised and could not give a reply. So to save him the consternation Nawab Khadim Hasan gave him an explanation:
If a leaf floats down a river and a stone is dropped on it, it sinks a little, then tilts and the stone falls off, and thus soon the leave alone is floating down the river. If you drop a stone in a river, it sinks. In fact if you tie anything to it, they both sink. But if a log floats down a river, you can grab it and it carries you to safety.
And so everyone in a lighter mood proceeded.
