In traditional Chinese philosophy, the Five Elements -wood, fire, earth, metal and water- describe how the universe works.
One of each generates another –
Wood feeds Fire. Fire creates Earth (ash). Earth bears Metal. Metal collects Water. Water nourishes Wood.
One of each restrains another –
Wood parts Earth (such as roots or trees can prevent soil erosion). Earth dams (or muddies or absorbs) Water. Water extinguishes Fire. Fire melts Metal. Metal chops Wood.
They can represent anything in the universe like the seasons, internal organs and political regimes. Their relationships is like allelopathy phenomenon. This expriment explore the relationship of water and ink. They bear, nourish, restrain, control each other.
