To the best of my knowledge, people come with that red chunri ( scarf worn by women over their head and shoulders) and they tie it somewhere around the temple ( usually there are places for that like a tree or some other stand). But people chose a door in this case and it catches a photographer's eye so easily.
Here are some shots from my other temple visit. Even though both these temples are some 1000 kilometres apart but the culture is similar. They levelled up and added bells as well...haha. (Devotees donate bells when their wishes get fulfilled).
Thanks for your kind words as always. 💙
