Two weekends running now I've been to circles where half the room is holding little copper rods — one in each hand, roughly pen-length, some with a bit of felt on the grip. And I have a mildly embarrassing confession: I bought a pair. And I cannot decide whether they do anything at all or whether I just spent forty dollars on the feeling of taking practice seriously.
Honest observations. With the rods, my hands hold the Janus Mudra spacing more steadily, because I'm not tempted to let the palms drift together. That part is real and probably just ergonomics. Whether the copper itself is doing anything to the field between the palms — I genuinely can't tell, and I suspect I'm the last person who could tell, given I wanted it to work when I paid.
So I'm asking the room. Helpful, or theatre? And if theatre — is theatre necessarily a bad thing if it helps you sit?
