At the end of one of my programmes, a lady danced for three hours in sheer celebration. Then she came and sat next to me and told me how happy she was. As she was drinking coffee, the beverage spilt on her beautiful saree. Immediately, she screamed, saying her joy from the three-hour dance was gone.
Looking at this incident, I learnt that three hours of happiness was invalidated by a sorrow lasting for a few seconds. If our mind can work like this, the reverse is also possible. The three hours of sorrow can be invalidated by a few seconds of joy.
