If you make the analogy between advices and “channeling” in the woo-woo psychic sense, there is general agreement on “clear channeling” being the way to go, from what little I’ve read. It is as close to a “law” as anyone (anything?) is willing to posture. There are conservation and symmetry laws all over the place, it seems. As above, so below. Do unto others. The usual.
Also, I'd say most people don't listen to most of my advice.
