If you’re walking near the dargah of Hazrat Nizamuddin Auliya in the neighbourhood of Nizamuddin Basti in Delhi, you might cross, but not notice, a grey door with a grey metal flower knob and no signage. If you are passing by on a Tuesday afternoon, you will, most likely, notice a group of children in descending order of height gathered outside the grey door. The children dart in every five minutes, running up the stairs behind the door that lead to the first and second floors of the building. They leave trails of chips, flowers, coins, plastic toys, and small footwear in their wake.
