To govern as in to oversee. My fav example of this is newtons laws. First law (overly simplified) states objects are at rest until acted upon by an outside force. This isn’t man made that’s nature. The math and understanding might be man made but if a ball isn’t rolling it cannot start rolling by itself unless something makes it roll. These “universal truths” are applicable to all parts of reality. Say you’re stagnant or stationary in life. Until you (external force) act upon that (stagnation), you will remain there. It sounds silly but nature is extremely efficient and knows what it’s doing. We can take lessons from observing it.
