A Harmonic Reaction ties two objects together: if one moves in space, so must the other. But crucially, their weight becomes that only of the heavier object—which is why Harmonics are so key to the Hierarchy’s machinery. “Weight paralletics,” they call it. The reason things like Transvects can work. Of course, I’m not concerned about how heavy we are, here. And in Res, people can’t be imbued. And a Harmonic Reaction with oneself isn’t possible. And Harmonics have nothing to do with somehow connecting to the gods-damned mind of another person.
