The lady was praying here to the Goddess Parvati, the wife of Siva at the wall of the entrance gate or Gopuram.

Here you put the red mark on your forehead before entering further the temple. Afterwards she was putting some Jasmine flowers at the silk dress of her beloved Goddess. (note the resemblance with the holy-water font in catholic churches and washing feet by Muslims)

The wall red, yellow colored from the powder, you better don't lean to it with your shirt, very difficult to wash out these colors.

You feel the strong devotion here ? It is always and everywhere present, even in daily life.
