In traditional gardens, the ponds and streams are carefully placed according to Buddhist geomancy, the art of putting things in the place most likely to attract good fortune. The rules for the placement of water were laid out in the first manual of Japanese gardens, the "Sakuteiki" ("Records of Garden Making"), in the 11th century. According to the "Sakuteiki", the water should enter the garden from the east or southeast and flow toward the west because the east is the home of the Green Dragon ("seiryu") an ancient Chinese divinity adapted in Japan, and the west is the home of the White Tiger, the divinity of the east. Water flowing from east to west will carry away evil, and the owner of the garden will be healthy and have a long life. According to the "Sakuteiki", another favorable arrangement is for the water to flow from north, which represents water in Buddhist cosmology, to the south, which represents fire, which are opposites (yin and yang) and therefore will bring good luck.
