I've featured so much work from various photographers, and seen so many photographs of the Nagas and pilgrims here and elsewhere, it's as if I've been there myself. I'm pretty sure these photographers who were at the Kumbh will either recognize each others work, or recognize the subjects.
However, here's the work of Fons Rademakers who's a physicist working at CERN (European Organization for Nuclear Research) in Geneva, where the largest particle accelerator is operated and where the World Wide Web began as a project. Fons leads a software project that provides programs for data processing and analysis, but started his connection with photography when 12 years old, and regards it as his passion next to physics and computing.
I would recommend to Fons that he ought to consider moving his many other photo galleries from SmugMug to his own website. They're certainly worth showing in a more professional medium.
