I am very interested in mudras--symbolic hand gestures. I bought a set of cards that has a different yoga mudra on each one. This is the courage mudra. I often look down and notice that my hands are curled up in this position. I find it very comforting, which makes sense because it is an anti-panic mudra. I thought that maybe there was some kind of trigger point on my fingers, but I've looked at all sorts of acupuncture maps, and I really haven't found anything.
