The killing of Narakasura: Celebrated as Naraka Chaturdashi, one day before Diwali, it commemorates the killing of the evil demon Narakasura, who wreaked havoc. Krishna's wife Satyabhama killed Narakasura during the Dwapara yuga. In another version of the belief, the demon was killed by Krishna or Krishna provoked his wife Satyabhama to kill Narshna, defeating Indradebated with the villagers about what their 'dharma' truly was. They were farmers, they should do their duty and concentrate on farming and protection of their cattle. He said that all human beings should do their 'karma' to the best of their ability and not pray for natural phenomenon. The villagers were convinced by Krishna, and did not proceed with the special puja (prayer). Indra was then angered, and flooded the village. Krishna lifted Mount Govardhan and held it up to protect the people and cattle from the rain. Indra finally accepted defeat and recognized Krishna as supreme. Although this aspect of Krishna's life is sometimes ignored it sets up the basis of the 'karma' philosophy later detailed in the Bhagavat Gita.So the story is that Light overshadowed darkness.
Today I have my indian sweets to eat and celebrate the power of Light over darkness.
