Nasreddin 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,” Nasreddin 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 Nasreddin everything he knows.
When he has finished, he says to Nasreddin:
‘Now that I have taught you everything, I would be proud to know how a fish saved your life.”
“Very simple,” says Nasreddin, “I was almost dying of hunger when I caught it and, thanks to that fish, I had enough food for three days.”
