On Bhogi old clothes and materials are thrown away and set on fire, marking the beginning of a new life. The second day, the 'Pongal' day, is celebrated by boiling fresh milk early in the morning and allowing it to boil over the vessel - a tradition that is the literal translation for Pongal. People also prepare savouries and sweets, visit each other's homes, and exchange greetings. The third day, Mattu Pongal, is meant to offer thanks to the cows and buffaloes, as they are used to plough the lands. On the last day, Kanum Pongal, people go out to picnic. Most families adorn the front of their homes with kolam (rangoli drawings) every day, but during Pongal, the kolams are amazing in their detail, colour and intricacy.
Here are the two most popular legends attached to Pongal celebration
The raising of Mount Govardhan
The first day of the festival Bhogi Pongal connected with Lord Indra (the Vedic God of clouds and rains) and with Lord Krishna. In previous times, people used to worship Lord Indra who was the King of the Gods. This honour given to Lord Indra made him full of pride and arrogance. When baby
The Banishment of Basava
Another legend associated with the festival relates to Lord Shiva. The third day of Pongal known as Mattu Pongal involves Lord Shiva and his mount, Nandi (Basava), the bull. According to the legend, Lord Shiva once asked the bull to go to the Earth and deliver a message to the people, to have an oil massage and bath daily and to eat food once a month. Basava mixed up the message, and told the people to have an oil massage and bath once a month, and to eat food daily. Enraged Shiva cursed Basava and said that due to this mistake there would be shortage of grains on Earth. He banished the bull to live on Earth forever in the form of cattle, and help people plough the fields. Thus, Mattu Pongal has an association with the cattle.
