Maham comes in the month of Maasi and the images of gods and goddesses
are taken out to the sea for a dip. In areas away from the coast, the
rivers or the tanks are the centres for this float festival.
The Maham is an annual event. But once in twelve
years, its importance exceeds bounds of imagination. When the planet
Guru or Jupiter enters Simha sign, the Kumba Mela festival
of south India is held at the famous Mahamaham tank at
Kumbakonam. Vast crowds gather in Kumbakonam and ordinary folk have a
dip in the tank, along with the saints and philosophers. All the
rivers of India are said to meet at Mahamaham Tank on this day and
so, a purificatory bath in this tank on this particular day is considered
equal to the combined effect of dips in all the holy rivers of India.
