This is not a meditation post, I promise.
Most meditation practices have you focus on your breath as part of the exercise. It’s always there (we hope), it’s always changing just a little, and it’s relatively easy to focus your attention on it. Some practitioners will say focus on where you feel it “the most” — being your stomach, your lungs, whatever.
When the monkey-mind isn’t successful in dragging me away from it, I focus on my sinuses. I find it absolutely fascinating what happens when I do.
