Duality

My understanding of duality is that the concept features interdependence and balance. One one doesn't disappear but makes room for the other. There's a continuum

I believe this can be seen in the relationship between life and death.

"Duality teaches us that every aspect of life is created from a balanced interaction of opposite and competing forces. Yet these forces are not just opposites; they are complementary. They do not cancel out each other, they merely balance each other like the dual wings of a bird."

you couldn’t understand what the concept of ‘up’ is without having a ‘down’ to compare and contrast to.  Same applies for in-out, hot-cold, sweet-sour, young-old, male-female, liberal-conservative, and on and on.

What could be a more profound example of duality than life and death? What could illustrate more succinctly how duality works in our world? In order to die, you must first be alive. We would never know what death is unless we are alive, which gives us a comparison.

“Remember the balance; the give-and-take of energy. The symbol of yin and yang is more than the integration of male and female. It’s also the balance of light and dark, soft and hard, active and passive, in and out, giver and receiver. You can’t have one without the other.”

-Brownell Landrum-

Yin corresponds to all that is feminine. It’s soft, warm, earthy, passive, absorbent, and dark. Yang represents the masculine side of things. It’s rough, dry, aerial, active, penetrating, and bright. Both elements and characteristics are present in everything that exists.

created by Laozi, an ancient writer who may or may not have actually existed.

They’re two opposing sides that don’t contradict each other but complement each other and depend on one another. One doesn’t want to impose itself on the other. Instead, they coexist in balance with each other.

Taoism says that constant change is the nature of everything.

If you want to follow the path to virtue, you have to allow these changes to happen, in nature and in your life.

Yin and yang represent this continuous change.

When the duality expressed in these two concepts is balanced, then you have harmony. Disharmony, on the other hand, is when one side of the duality dominates over the other.

Interdependence.

They maintain a dynamic equilibrium.

Don’t try to make everything positive.
