“This of the universal laws is also called the Law of Opposites. The Law of Polarity states that everything in the universe has two opposite poles, and these poles are necessary for creation and manifestation to occur.
This law suggests that there cannot be one
without the other and that all things contain both positive and negative aspects. It emphasizes the importance of finding balance and harmony between these polarities.
This law suggests that we can only understand and appreciate something by experiencing its opposite. For example, we can only appreciate happiness by experiencing sadness.”

Teaching The Law Of One says, “In order to successfully graduate from the 3rd density, consciousness can and must become polarized toward one pole or the other: ‘service-to-others’ or ‘service-to-self.’
The purpose of polarity is to develop the potential to do work. This work drives evolution forward and galvanizes the development of will and faith, creating a more vivid and intensive experience of the Creator knowing itself. Called the axis upon which the creation turns, the higher densities do their work due to the polarity gained in this choice until the 6th density when the polarities are released. 
The Law Of One blinks neither at the light or the darkness, but is available for service-to-others and service-to-self.
In 6th density, the density of unity, the positive and negative paths must needs take in each other for all now must be seen as love/light and light/love. This is not difficult for the positive polarity, which sends love and light to all other-selves. It is difficult enough for service-to-self polarized entities that at some point the negative polarity is abandoned.”
