Lakhs of pilgrims, including some NRIs, have gathered at the Triveni Sangam, the confluence of the Ganga, Yamuna, and the mythical Saraswati river, to take part in the first 'Amrit Snan' of the Maha Kumbh Mela in Prayagraj on Makar Sankranti. This marks the largest religious gathering in the world, attracting devotees from across the country and abroad for a spiritual experience.
