The Tradition of Gambling
The tradition of gambling on Diwali also has a legend behind it. It is believed that on this day, Goddess Parvati played dice with her husband Lord Shiva, and she decreed that whosoever gambled on Diwali night would prosper throughout the ensuing year.
Diwali is associated with wealth and prosperity in many ways, and the festival of 'Dhanteras' is celebrated two days before the festival of lights.
