The Universal laws are absolutely necessary for a metaphysical system of the universe to work. In other words, all the laws, the concept of balance within the universe, the theory of there being a Divine universe, reincarnation, and so on, all these ideas can only work or function if there are laws that govern cause and effect. And like all things, this concept is a theory. As mortal beings, we can only 'know' facts based on our inner knowingness or belief. These laws are no more factual or invalid than the mythology of the creation of the universe in the Norse Eddas, or the Christian Bible.With that said, what is the theory of Universal Law & Chaos? Before we can examine the Universal Laws, we need to understand what Universal Laws are and how they relate to Universal Chaos. And yes there are both. This is how balance is created within the universe.
Universal Laws were created with 'Creation', whether mankind has discovered them or not. No other laws are necessary to run the Universe. These principles have no exception (as man made laws do) and if events, situations, objects, persons, phenomena and mother nature act as if an exception exists, it is only because humanity does not understand the law in its entirety. These laws are basically rules of nature, or more accurately stated, rules of the Divine Universe. Like laws of science (gravity, relativity, etc.), the Universe laws exist to provide order in nature. Without that order, we would have no purpose, no basic concept of knowledge, wisdom or life.
Universal Chaos - where Universal Laws provide order, chaos provides balance. There are theories that Chaos existed before order was established in the universe. That the Universe was born out of chaos and thus chaos is in all things. Keep in mind that Metaphysical concepts are from the great masters (Pythagorus, Aristotle, Plato). The words and meanings are Greek. Chaos, is the creation of perfectness consisting of indestructible, intelligent, energetic atoms (and smaller particles) not having order. Chaos is the essence of all things made in the universes, the formless void of primordial matter. Some call it chaos, others call it perfectness as mankind knows no other.
If life were totally preordained, then what's the purpose of learning? What's the purpose of growing and expanding your awareness? The outcome is already known. So why not skip the process and just get to the result. But that's the point. Life IS NOT preordained. Your free will and choice create the chaos that by your decisions direct the outcome. You have the ability to continue your construction and spiritual evolution, or destroy it and face the same situation over and over until the lesson is learned.
