Lord Vishnu carries the kumbh or the pot full of nectar that would grant immortality as he is chased by the Asuras, the evil forces. During the chase the nectar spills a little in 4 places on the mortal earth. Allahabad is believed to be one of the four places where the nectar fell and it is also the place where three rivers converge.
Every 12 years the Kumbh Mela comes to Allahabad and with it comes millions of devotees who want to purify their soul and gain immortality with their actions. A dip in the river means so much more than a bath. The chants of the holy men echoes more the words and the sight of swaying elephants calms the mind. Kumbh Mela is one of the biggest and most ancient festivals in the world. In 2013, more than 120 million people came together in their faith.
So Farmer Falgu had gone on a trip to find quiet, he had gone to the market with innumerable mishaps on the way and he went kite-flying too. So in the fourth book we decided he will go to the Kumbh Mela.
In this story, Farmer Falgu like every devotee who visits the festival wants to dip in the river, listen to the chants, watch the elephants and eat some delicious local food. Does he get to do all that? You have to find out by reading the book.
