ONE

The Yin-Yang: It looks like two distinct forces or entities trying to dominate as well as try become the other at the same time. Each is in continuous action. But either of the two would have no objective or movement without the other. Call the two forces/entities whatever you like: White & Black; Passive & Active; Light & Dark; Good & Evil; Male & Female; Strong & Weak.

The Yin and the Yang are enclosed or rather confined into ONE circle. The ONE can be regarded as Singularity (Adwaitham) while the Yin-Yang forms represent Duality (Dwaitham). The two are part of ONE and ONE creates the two. And this is the simplest representation of the relationship between duality and singularity.

Extending the above concept a little more further: In the beginning, there is nothing else but ONE. Then something arose from this ONE, two things to start with. Then these two in turn created the rest of the complexities. So in my understanding; all intricacies, harmonies, clashes, causes and effects; that we can imagine arise from and exist within the ONE big system. I call this ONE the UNIVERSE. Some prefer to call the bigger system the Universal spirit or Universal consciousness or God. Most religious books also corroborate this concept.

But why did ONE complicate itself by dividing into two by its own intent? Probably just for entertainment ;-)
