I went to the biggest fair in the world and I'm still processing what I saw

So in January 2025 I went to Prayagraj, a city in India, to visit the Mahakumbh fair. It happens once every 12 years, but the one that happened in 2025 comes only once every 144 years. It's the biggest fair in the world. I went there with my father and some of his friends. I was seeing constant news coverage of it before going, and some tragic incident had happened just before we went, so I was kind of feared and also excited at the same time. On February 6 we boarded the train and reached there on 7th February. The system was totally chaotic which is normal because of the huge crowd. In total about 650 million people attended the fair which is more than the population of the entire USA. The thing that amazed me was seeing the diversity of my country. Literally from every corner of the country people came. I just looked at their dress, unique food, talking, manners etc. I was feeling like I came into another kind of world. No one matched with the other. There were different ashramas where saints from different states came and they were practicing their unique rituals. Some were completely without any clothes. The 2 days which I spent there was filled with total astonishment. I am happy that I became part of such a thing which is kind of rare.
