Bhogi Pandigai, the first day of the Pongal cycle, signifies renewal before the harvest season. Celebrated as a Hindu festival, it involves discarding old items and lighting a bonfire, symbolizing a fresh start and leaving behind the past. The festival is linked to agrarian traditions, honoring deities Indra (rain) and Surya (sun), crucial for farming. Families engage in cleaning and sorting, embracing the theme of new beginnings and preparing for the upcoming crops with hope.
