The easiest way to understand the dynamic between two individuals, is through their animal totems.
If one has a tiger as their essence self, and a bear as their companion self, and the other has a horse as the essence self, and a deer as the companion self, we can see exactly how and where these two individuals would face challenges in their relationship and where they would thrive as well.
The horse is independent and strong. It is majestic and resilient. The tiger is magnetic and fierce. They would most likely face power struggles in their dynamic. But they are also a powerful force when united against a challenge.
This is just an example so you can understand how to analyze relationships through that simple totem test (highlights Totem).
When you dare to love, don't half ass it. Love completely.
No matter how many flaws you see in your partner, they are a direct mirror of your current state of consciousness.
