Pongal is a significant harvest festival of Southern India, especially Tamil Nandu.Pongal in Tamil means ‘to boil over.’ Hence, as a custom, the fresh harvest of rice is cooked in boiling milk and this special dish is then offered to Sun God. The boiling over of milk in the clay pot symbolizes material abundance for the household. Pongal is the festival to thank Sun God for giving sufficient sunlight,which is most essential for good harvest. This four-day long festival is celebrated with great enthusiasm and zeal to show our gratitude towards Sun God and Mother Nature.
