2.108

「『一一池水，七寶所成。其寶柔軟，從如意珠玉生。』」上二句明色相。池塘階岸眾寶合成，池中泉水色亦如然，故云七寶成也。下二句示出處。每一池心各有珠玉，泉從玉出，流落池中常時盈滿。三、明流渠。

"‘The water of each pond is formed of the seven jewels. The jewels are soft, produced from wish-fulfilling gems.’" The upper two sentences explain the colors and characteristics. The pond's banks and steps are formed of various jewels, and the color of the spring water in the pond is also like this; hence it is said to be "formed of the seven jewels." The lower two sentences show their source. In the center of each pond there are wish-fulfilling gems; the springs issue from the gems and flow down into the ponds, remaining constantly full. Third, explaining the channels.
