WTF is Yoga anyway?
Yoga means union specifically in reference to the union between you and the divine whatever that might mean to you.
There is also reference to the Sanskrit word for yoke which is yuj. A yoke is a physical device used to join cattle. It might make more sense to think of Yoga as the yoke which is both the device and technique to calm the cattle or horses down. It works in this way so that you could focus them and do the work of war. Only in modern reference, you are the cattle or horse. Yoga allows you to do the work while maintaining connection and calm.
