Mulla (Master) Nasrudin was devised by the dervishes partly for the purpose of thinking about situations and trying to make the thought process of these moments clear.
On the surface a lot of the Nasrudin stories may be used as jokes, but the stories of Mullah Nasrudin can be understood on multiple levels.
The wisdom of Nasrudin can sometimes form a mental bridge between the mundane and profound, turning the ridiculous into reality.
The stories have a way of moving the participant through new thought patterns to reveal unexpected solutions to problems.
Nobody really knows who Mullah Nasrudin was, where he lived, or when. This is truly in character, for the whole intention is to provide a figure who cannot really be characterized, and who is timeless.
