I have a theory.
After reading an article about the THREE brains in our bodies (yes, three), I am considering that when Mercury goes retrograde, we really only have problems when we rely too heavily on one of those brains -- the one in our heads.
But, given the fact that we also have a brain in our belly (our source of gut instinct) and a brain in our heart (our source of feeling response), we are not just cut adrift from our ability to navigate this reality when Mercury is retrograde. True, our rational brains (which Mercury represents) may not be functioning fully, and events may not unfold according to the expectations of that rational mind, but our other two brains are still fully engaged and ready to take the reins.
We have a good three-plus weeks to play with this theory. I'm going to give it a try.
