While the others breakfasted on suyou cha and tsampa, I walked down to the lakeside. The water was crystal clear, showing the blue-grey stones on the bottom, receding into pale sandy depths. The surface of the lake was absolutely still, and appeared to be covered with a fine coating of dust. I witnessed an unusual and startling visual effect. When the sun’s rays first appeared over the ridge, the surface of the lake became a perfect mirror reflecting the snowy mountain and autumnal forest colours of greens, yellows and reds and browns. However, as soon as the sun’s rays directly touched the lake, the mirror reflection was instantly and dramatically transformed into a window, revealing the sparkling perception of its depths. I threw in a small pebble and watched the concentric rings of its ripples swimming and expanding as shadows on the bottom of the lake. If there was a monster down there it must be keeping very still, I thought.
