Anavatapta, or Heatless Lake, is the lake lying at the center of the world, the source of the four great rivers:
Flowery forests of jewel trees circle the lake, and when the sun comes out, they reflect everything in and outside the lake, joining the reflections and radiance into a network of light. Myriad things are like this—far and near, high and low, broad and narrow, coarse and fine, even down to the tiniest grain of sand and mote of dust, all being beautiful jewels, clearly mirroring lights, all reflected in the orb of the sun, and all reflecting and rereflecting each other; these reflections, neither increasing nor decreasing, neither merged nor separated, are clearly visible as though they were the original substance itself.
