Even before midnight, devotees from different walks of life and parts of the country began to pour into Sangam city to take holy dip on Mahashivratri, the great night of Lord Shiva and the last bathing day in the one-and a-half-month-long Kumbh Mela. Till Monday evening, more than 1 crore devotees had taken a holy dip in the Sangam area, officials said. The bathing ghats brimmed with colour in the morning. Late-night showers in parts of the holy city failed to dampen the spirit of the pilgrims. As the sun came out, devotees enthusiastically greeted the sun, while some offered obeisance to the Sun God with traditional 'Yoga asanas'. According to Hindu mythology, Mahashivratri symbolises the last holy bath of Kalpvasis, who spend the month of Magh -- the period of austerity -- in minimal means. Kumbh is one of the largest religious gatherings in the world. It is held once in every 12 years. This time it began on January 15 on Makar Sankranti. There are six bathing dates. Of these, shahi snaans are held on Makar Sankranti, Mauni Amawasya and Basant Panchami. Parv snaans are held on Paush Poornima and Maghi Poornima.
