I feel like this is a topic that could live forever.
In kung fu we always began facing North.
In that sense X+ is North.
Why? For one it means you’re paying attention, you’re thinking, you’re aware of the world and where you are and nature. Connecting with nature.
Another reason might be if it’s the morning do you want to face East with the sun in your eyes? Or West at sundown? Not a good way to begin. In Samurai 3, the opponent fell because he wasn’t aware of where the sun was and the hero was. He used it to his advantage, so the other guy couldn’t see.
Maybe you are the needle and the most natural thing you can do is face north. It can represent the path of least resistance.
And if X+ is North, by default the sun is somewhat South. Does that mean we’re in the northern hemisphere? Maybe it’s an alien planet where the equator is too hot and so everyone settles toward the poles. They say in the north pole the sun only rises and sets once a year. Where does it set from? How do you measure direction if you’re at the north pole? There is no East or West, only South.
I had no intention of writing all this, but it’s kind of fascinating.
