Everything in the world, nature, universe,… is in some state of duality.

That’s my perception.

Everything seems to seek balance. When it is achieved, it becomes static (flatline) until the energy is transformed to another form, and sufficiently generated for another ‘repeated’ cycle.

We should seek balance, but understand that the differences between two polarities represent the energy for (more or less) movement.

Principle of Duality also shows that you can’t have more negative than positive charge. Every functional system in nature adheres to nature’s laws (one of the is Newton’s third law of motion). You cannot create or destroy energy, and every action demands opposite proportional reaction.

‘No such thing as a free lunch’ holds true both ways.
