25 The Constructive Cycle

beginning with the Fire cycle: whenever the fire element become extreme it will create the earth element. This can be seen in nature, as a fire will produce ash.
Earth in turn is capable of production the metal element. Under pressure the earth will condense minerals into metal ore, which is mined from the ground.
Metal is the element that gives birth to the water element. This transition is more obscure than the others, however, when you place metal under extreme conditions, such as high heat (yang) the metal will turn into liquid. Likewise when you place metal into freezing (yin) conditions, the molecules that make up metal will retract and attract miniature drops of condensation.
Water is the element that feeds and nourishes the wood element, as can be seen daily in nature, where plants will wilt and eventually die if they are staved of water.
Wood is the element that gives birth to the fire element, just as logs are used to fuel a fir.
