There are many "Cosmic Laws" or forces that operate or apply to us and nothing you can do will change this. The wisest approach is to first be aware of what they are, understand them, harness their energy and relax as they work in your life as you intend them to by respecting their power.
There are quite a few "Cosmic Laws" and here are nine that most of us are somewhat familiar with:
1. Law of Mind - the All is mind; the Universe is mental.
2. The Law of Cause and Effect.
3. Law of Correspondence - "as above, so below, as below, so above."
4. The Law of Resonance and Attraction - like attracts like. You could call this attunement or alignment.
5. The Law of Harmony and Balance.
6. Law of Vibration - "nothing rests, everything moves, everything vibrates."
7. Law of Rhythm - rhythm equalizes.
8. Law of Polarity - contrasting aspects. Like and unlike are the same.
9. Law of Gender - yin and yang principle in everything.
While these laws go much deeper than I described and there are many more, this is a start in understanding the major forces that act on us and that we can harness for our own good. Get to know these laws, these inescapable forces and how they truly work as they will help you see the inner workings of how and why things happen. They will bring you clarity and ultimately, peace.
