Kumba Mela 2013...a once in 12 year religious pilgrimage going at Allahabad, Uttara pradesh. The largest single gathering of humanity on earth. Kumbh Mela is a mass Hindu pilgrimage. My brother attended the Kumbh mela and performed the snan on Feb 10th which is a main bathing date. he had no words to explain about the pilgrimage experience which was both good and bad.
This is pure belief. There is no scientific proof any where. This is happening since centuries.
Allahabad is an ancient city of India, considered holy because it is built on the confluence (Sangam) of the rivers Ganga, Yamuna and the mythical Saraswati.
