Mulla Nasrudin is walking past a cave when he sees a yogi, deep in meditation, and he asks the yogi what he is searching for.
The yogi says: ‘I study the animals and have learned many lessons from them that can transform a man’s life.’
‘A fish once saved my life,’ Nasrudin replies. ‘If you teach me everything you know, I will tell you how it happened.’
The Yogi is astonished; only a holy man could be saved by a fish. And he decides to teach Nasrudin everything he knows.
When he has finished, he says to Nasrudin:
‘Now that I have taught you everything, I would be proud to know how a fish saved your life.’
‘Very simple,’ says Nasrudin, ‘I was almost dying of hunger when I caught it and, thanks to that fish, I had enough food for three days.’
