Neak Pean was originally designed for medical purposes, as it is one of the many hospitals that Jayavarman VII built. It is based on the ancient Hindu belief of balance. Four connected pools represent Water, Earth, Fire and Wind. The ancients believed that going into these pools would balance the elements in the bather, thus curing disease. In the middle of the four healing ponds is the central water source. There is a statue of Balaha (Bodhisattva Guanyin transformed into a horse), as a symbol of drowning prevention.
