The cave is long and dark, a single candle at the far end and the light spilling in at the entrance are the only sources of light. I shine my flashlight over the walls, there in the corner is a raised platform in a kind of alcove. On it a number of Buddha figurines in faded gold against the bare rock walls. The only sound is the wirr click of my camera and the soft humming of the ticket lady at the entrance. I put down the camera, turn off the flashlight and just listen for some moments in the darkness .
