Stream flowing next to the Guru Nanak Taposthal between Menchukha and Yorlung, Arunachal Pradesh. At a particular spot along this stream, you’re supposed to dip your whole arm ad sometimes top of your body as well, to retrieve a bunch of pebbles – if you get white pebbles, it means your heart is clean and you’re going to have good luck etc. but if you get black pebbles, it means the opposite and you can have three tries only. It was, of course, more interested in making photos.
