My teacher recently said that being in uncertainty is what it means to be human. We quite literally NEVER know what's going to happen next. No matter how much we PLAN, organize and try to orchestrate our destiny, we must move with the current of whatever life offers.
Yoga makes us more PLIABLE. Clearly this applies in a physical sense--yoga ASANA is about making SPACE. But hopefully, it's true of our mental capacity too. FLUIDITY over RIGIDITY in our thoughts, feelings, reactions is preferred. So that we "will not break, but will bend, like the graceful willow, as inevitable change occurs." (Swami Ma)
INVERSIONS practices teach us to reframe our perspective. Going upside down can flip our understanding of what we are capable of, what we can accomplish.
