I noticed this painted on a wall next to a small restaurant in Benares. The restaurant is very close to the Kal-Bhairav temple, actually a stone's throw away — if one throws in the right direction and makes the stone take a couple of turns around tight corners in the narrow alleys that lead to the temple.
Back to the painting: I have tried fathoming what it was that the artist was trying to convey. But it's umm. . . well I found it a bit diffcult to stop smirking horribly and laughing when I saw the painting for the first time much to the chagrin of my friend.
A week and some days later, I may no longer laugh but the grin persists.
