there is a story of a guru who had stupid disciples.So any work that the guru wil give the disciples would do the opposite. once the guru daughter was getting married and he told the disciples to whitewash the front of the house .
the disciples went and whitewashed the opposite house. the guru asked "what did u do ?" now the baaraat is coming . quickly whitewash the front.
when the guest arrived, the disciples caught hold of each guest and started painting them.the guests were so annoyed that they cancelled the wedding .the guru was upset. but then he later found out tht the groom was not mentally sane.
the lesson : even though the disciples were stupid ,something good came out of all their mistakes.
