Tihar, the festival of lights is one of the most liked and dazzling of all Hindu festivals. Actually In this festival we worships Goddess Laxmi, the Goddess of wealth. During the festival all the houses in the city and villages are decorated with lit oil lamps. Thus during the night the entire village or city looks like a sparkling diamond. This festival is celebrated in five days starting from the thirteenth day of the waning moon in October. We also refer to tihar as 'YamaPanchak' which literally means 'the five days of the underworld lord'. We also worship 'yamaraj' in different forms in these five days. In other words this festival is meant for life and prosperity.
Goddess Laxmi is the wife of almighty Lord Vishnu. She was formed from the ocean and she has all the wealth of the seas. She sits on a full-grown lotus and her steed is the owl. On the third day of the festival at the stroke of midnight she makes a world tour on her owl looking how she is worshipped.
There is a story, which tells why this revelry is celebrated so .Once there was a king who was living his last days of life. His astrologer had told him that a serpent would come and take his life away. The king did not want to die so he has asked the astrologer if there was any way to escape death. The king was advised to sleep with lit oil lamps all around his bed and decorate the palace with oil lamps on laxmi puja day. So goddess laxmi would talk to the serpent not to take his life. It did happen, the serpent was convinced by goddess laxmi. The serpent took the king to Yama Raj and told him that it was not yet the king's time to come to the underworld. So Yama Raj opened his ledger and in it the kings remaining age was written zero, but the serpent cleverly put seven before zero. Thus the king lived for seventy more years. So onwards tihar is widely celebrated worshipping the underworld and goddess laxmi.
