Each day of Pongal has a slightly different focus and theme:
Today is called Bhogi Pongal, which means "enjoy abundance"; it's a day to honor the rain god, Indra, for providing rain for the harvest. Today farmers anoint their plows and sickles with sandalwood paste to bless them, then bring in the fresh harvest of rice and sugar cane.
The second day is called Surya Pongal, named for the sun god, Lord Surya. On this day people cook sweet rice at sunrise, and watch for the rice to bubble out of the clay pot. The boiling over symbolizes good luck and prosperity for the family.
The third day is Mattu Pongal, focusing on the cattle who pull the plows. (Mattu means "cow".) The cows are cleaned, decorated and fed treats.
The fourth day is Kanum Pongal. Kanum means "to view": It's a day to visit friends and family.
