The universe is filled with opposing sides and opposing forces.
There is always more than one way to see a situation, and more than one way to solve a problem. Two things that seem like opposites can both be true.
Everything and every person is connected in some way.
The waves and the ocean are one. The slightest move of the butterfly affects the furthest star.
Change is the only constant.
Meaning and truth evolve over time. Each moment is new; reality itself changes with each moment.
Change is transactional.
What we do influences our environment and other people in it. The environment and other people influence us.
