A posture question I can't seem to solve on my own. When I set the Janus Mudra — upper palm down, lower palm up, both at the solar plexus — my lower hand won't stay put. Over a five or six minute sit it slowly drifts inward, toward my body, until the gap between the palms has almost closed and my lower hand is nearly touching my stomach. :)
I only notice once it's happened. Then I reset, and a couple of minutes later it's crept in again. My question is really: does the drift mean something, or is it just a slack-arm problem? Is the field still doing whatever it does if the geometry keeps collapsing? I don't want to overread it, but I also don't want to keep fighting my own hand if the drift is telling me something.
