We live in duality.
We love good people, and hate bad people,
We eat nutritious food, and junk food also,
We say 'my religion' is better,
Than 'your religion',
The opposite person,
Utters the same slogan.
There is lots of duality in the cosmos,
In matter, in air, in energy,
In electricity,
Space-time is a mysterious duality.
We ourselves, are some good, some bad,
We often exercise double standards,
We often find out at least two options,
We mostly live in pairs.
Pair-bonding is in the Nature,
It has become the ESS,
The Evolutionary Stable Strategy,
The result is propagation,
Of species, and humans,
For millions of years.
