This autumnal ritual was different from the conventional Durga Puja, which is usually celebrated in the springtime. So, this Puja is also known as 'akal-bodhan' or out-of-season ('akal') worship ('bodhan'). Thus goes the story of Lord Rama, who first worshipped the 'Mahishasura Mardini' or the slayer of the buffalo-demon, by offering 108 blue lotuses and lighting 108 lamps, at this time of the year.
