Yin Yang Theory
Simply opposites – black and white. Every characteristic of Yin is the polar opposite or the contrasting quality of Yang. Together they symbolise a cycle of constant change:
• dark to light
• feminine to masculine
• winter to summer
• cold to hot
• wet to dry
• aggressive to passive
• absolute to infinite etc
Whilst polar opposites, Yin / Yang also complement each other

The 5 Elements
(Wu Xing)
Yin and Yang represent duality, although these 2 parts together are ultimately one whole (Taiji). Yin and Yang are united pairs – they cannot exist without the other. Like two sides of a coin, separated but joined. To be in balance, both have to be present – known as ‘unity in duality’. The Chinese do not put the word ‘and’ between Yin Yang to demonstrate this unity.
Interactions of Yin Yang
- Opposites
- Divisible but inseparable
- Rooted in each other
- Counterbalance each other
- Mutually transform each other
In Yin Yang Theory, the Yin Yang state are never static, only temporary:
Yin is born out of Yang
↓
grows
↓
peaks
↓
then exhausts into Yang
↓
Yang is then born out of Yin

then exhausts into Yin
Within the darkness of Yin, there is small part of the light of Yang and within the brightness of Yang, there is a small part that is dark. This means there must always be unsteadiness within balance.
The most common Yin/Yang symbol (also known as the Taiji Diagram or the Taijitu) has a black dot in the middle of the white area and a white dot in the middle of the black area.
Another older symbol for these is the unbroken or solid line for Yang and the broken or divided line for Ying. These come from the diagrams used in the I Ching – The Book of Changes.
In Feng Shui, Yin and Yang is present in your surrounding environment. Within the 5 Element Theory they are used with each Element e.g. Yin Water or Yang Water.
Yin Water would be a gentle stream or bubbling brook whereas Yang Water would be a roaring ocean or crashing waves on the shore.
