Everything in the universe has its opposite. The divine has its diabolic. There would be no inside of a box without an outside. There is an up to every down and there is a down to every up. You have a right and left side to your body, a front and a back.
The Law of Polarity not only states that everything has an opposite but also that it is equal as the opposite. If it was three feet from the floor up to the table, it would be three feet from the table down to the floor. If it is 1692 km from Melbourne to Brisbane, by law it must be 1692 km from Brisbane to Melbourne, it could not be any other way.
Napoleon Hill, author of Think and Grow Rich, said “Every adversity, every failure, and every heartache carries with it the seed of an equivalent or greater benefit.”
In more of a definition-style, the Law of Polarity states that everything that exists has an equal and exact opposite. To put it even stronger: for anything to exist there has to be an equal and exact opposite. The Yin/Yang symbol is a good example of polarity. The Chinese believe that everything has its masculine (yang) and feminine (yin) principles, and that these are the basis for all creation.
Likewise, circumstances are not negative or positive, circumstances are neutral. If something you considered bad happens in your life, there has to be something good about it. It is your thinking, your mental state, your perspective, that makes a circumstance positive or negative.
It helps to remember that, within every situation, the spectrum of possibilities includes your ability to experience fulfillment in your life from the outcome of any number of circumstances.
