Super-Ego: most well rounded couple?

[JWC3]

I think duality is much about balance, a flowing composition of two elements that fuel one another at the rate of which the composition is fulfilled.

I was more insinuating that the balance existed externally through the application of a partner with complimenting functions rather than internal realization through super-ego relations. Or rather that assuming it was about internal balance, which I agree is the case, than an environment where you're free to practice using such functions without fear of admonishment would be far more beneficial.

It's less about something inside you that you realize and more about having a relationship or environment that you are free to be bad at certain functions in for the sake of your own development.

So duality may not be balanced, though it does produce it. It's less important that one partner is much better at certain functions than it is that they don't mind when you are bad at those same functions. So my emphasis is less on the existing balance and placed on the comfort instead as more beneficial though both likely play some part in creating that comfort.

EDIT: @polikujm I'm responding to the assertion that the two relations could be equally balanced by saying that it's important to remember that one is still more comfortable and that may produce balance quickly even if the other is innately 'more' balanced.
