Filmed in Allahabad and Varanasi during the 2019 Kumbh Mela Hindu pilgrimage, where an estimated 120 million pilgrims gathered between January and March. The Kumbh Mela occurs once every 6 and 12 years, and is the largest gathering of humans on the planet. " यागः सर्वतीर्थेभ्यः प्रभवत्यधिकं विभो ॥ श्रवणात् तस्य तीर्थस्य नामसंकीर्तनादपि । मृत्तिकालम्भनाद्वापि नरः पापात् प्रमुच्यते ॥ O King ! Prayag (Allahabad) is the superior-most among all pilgrimage places. If its greatness is heard, its Name is chanted or if its soil is smeared on the body, man will be liberated from all sins. ~ Mahabharat, Parva 3, Adhyaya 83, Shloka 74, 75
