Sitting one day in the teahouse, Mulla Nasrudin heard the rhetoric of a travelling scholar. He was arguing for the existence of God; questioned by one of the company on some point the scholar drew a book from his pocket and banged it on the table:
This is my evidence! AND I wrote it myself!
A man who could not only read but write was a rarity, and a man who had written a book...!
The villagers treated the pundit with profound respect - and of course Mulla Nasrudin was impressed! Some days later Mulla appeared at the teahouse and asked whether anyone wanted to buy a house.
Tell us something about it Mulla, the people asked him. For we did not even know that you had a house of your own.
Actions speak louder than words! shouted Mulla, and from his pocket he took a brick and hurled it on the table in front of them.
This is my evidence! Examine it for quality - and I built the house myself!
There are things which cannot be proved, and there is no evidence for them because they are self-evident, and to try to prove them is ridiculous, and the effort shows that one is not acquainted with them. Such are all the proofs of God.
