I visited Bakhtiyar Kaki's dargah in Mehrauli on a Thursday, the busiest day at Sufi shrines, and here are a few images of the scenes and crowds, to complement the images and descriptions in the main post below.
North entrance to the dargah
Passageway leading into the dargah complex
Bakhtiyar Kaki's tomb
Women are not allowed into the courtyard of Kaki's tomb, and can only view the tomb through this screen
The large dargah complex has many courtyards and open spaces, some crowded and some more leisurely, like this one
Makeshift marketplace at the western entrance to the dargah
Food being prepared for pilgrims and visitors to the dargah, in front of the Zafar Mahal gateway
