Last night I spent several hours communicating with two friends, and it soon became apparent to me that what we were engaged in was a true meeting of the minds, or if you will a meeting of the Mind with itself, attempting to reconcile varying points of view. This is part of the homeostatic self regulating function of consciousness itself, checking in with itself to align the perspectives and allowing information flow from one mind module to another as needed.
One thing that I was struck with was that the very act of communicating, which we were doing with facility, must have been learned at some point, and I don't think it was in school, at least any school that I can remember. It was almost as if this triadic configuration was a pattern in itself that had been practiced, different from the dyadic and different from larger groups. If I were to guess I'd say that the monad, the dyad, the triad, the tetrad, the pentad, the sextad, and the septad are the fundamental building blocks of communication, and each has a somewhat different set of strategies associated with it. Obviously, there are some principles that cut across all the root structures: for example, the ability to listen (even to oneself, in the case of the monad). But there are some that are unique to each structure.
For example, in the case of the triad where you are one member, if someone is saying something, you can only focus on them and not the other person. You are not going to be able to have A and B in your awareness at the same moment. But you cannot go too long without referencing the one you are not focusing on. This ability to recoup the connection with the member that is subordinate in a given moment is one of those essentials to learning how to communicate in a triad. As I say, we learned this skill a long, long time ago. And though the place and circumstance of this training may be lost in the mists of time, it bears feeling into the fact that it happened, and that it is a clue to the hidden mysteries behind our bodily incarnation in this plane.
