With low self esteem we behave in blaming, placating, superreasonable or irrelevant ways. When using open communicatie we're congruent with our selves, and we can level out (the amplitude).
The more we learn to (re)cognize stances and their finer shades, the better and faster we can level out our responses when, as we humans tend to have happen to us, we suddenly find ourselves in the middle of incongruence (again). Quite a balancing act and lots of practice, practice, practice ....
With a lack of esteemed communication in our system, our rules become hidden, outdated, inhumane, written in stone. A likely effect is that people change their needs to conform to established rules. Some may believe that a good idea. In the long run, it leads to Only Might being Right. With open communication, the rules are clear to all, up to date, change as the need arises, and people noticeably practice the five freedoms and will comment on anything that attracts and repels them, in congruent ways.
With hidden rules written in stone, results will be accidental, chaotic, destructive and unfitting. In a congruent system, with open communication on rules, the results will be in the flow.
