Dualism
The yin-yang symbol represents the interplay of opposites. Not two separate parts. Like sides of a coin. Like day and night — inseparable because they are part of the same cycle.
Yin and yang are complementary forces. Not static. Always in flux and transformation. What seems opposite is actually interconnected.
-
Yin is associated with darkness, chaos, and femininity. The hidden, the intuitive, the nurturing.
-
Yang symbolizes light, order, and masculinity. The visible, the rational, the active.

The small circle within each half — yin contains a seed of yang, and yang contains a seed of yin. Nothing is purely one or the other.
The wheel turns on its own. The poles flow into each other, and you can’t get stuck on either for long. Don’t cling to one half — watch the whole thing turn.
