Bali has ancient water irrigation system, “Subak” which has proven to be near perfect. The philosophy guiding it is harmony. Mutual agreements govern planting cycles, the division of water and the responsibilities of members. It’s defined by the Hindu concept of “tri hita karana”, or “the three causes of happiness”. It states that people must be in harmony with their fellow human beings, with the environment and with God. Through the eyes of Pak Puja, the Subak leader, the documentary narrates the story of how it is possible for humans to live in harmony with their environment through traditional methods and mutual cooperation.
