I personally think that Emotional/ Solar Plexus Center is one of the Centers which is easiest to distinguish. Even if you don’t have the Human Design Chart of a person, you still have a high opportunity to guess correctly whether his/her Emotional Center is defined.

Let me explain the reason by talking about the characteristics of the people with undefined Emotional Center first. Since their emotional energy is not stable, they always give a clam impression to others, sometimes even too clam that you may think they are cruel. People with defined Emotional Center often feel frustrated of communicating with them, as they always seem indifferent to all big incidents, also they do not show any happiness when you want to please them. Actually, people with undefined Emotional Center also often feel frustrated and confused, since they cannot control the chemical reactions inside their bodies and sometimes become impulsed and make huge mistakes.
If you have an open Emotional Center (there are no defined gates in it), people will feel you are even more unemotional. You often do not understand what you feel inside and have a difficulty of having an emotional attachment with others.
For people with defined Emotional Center, their expressions can always reflect their emotions and they can easily affect others’ emotions. They may not know how to solve their emotional problems, but they always understand what they feel inside. When they were teenagers, they often trapped by their emotional fluctuations and some of them might have a thought of committing suicide. However, most of them will feel more peaceful when they grow up as they have learnt how to deal with their emotions. Be aware that Emotional Center connects with kidneys, so if you have negative emotions for a long time, you may have edema problem.
Since there are 50% people have undefined Emotional Center, half of the population is restricted by people with defined Emotional Center. The situation always happens in couples’ relationship, the one with undefined Emotional Center will feel incompetent if their partner lose their temper. As they cannot understand the emotion of their partner, they are often “controlled” and get lost. The popular “Emotional blackmail” saying can reflect this kind of situation.
Since it is easy to make huge mistakes when people reach emotional imbalance, if you have undefined Emotional Center and is surrounded by negative energy, you must leave, otherwise you may get lost. If you face this situation for a long time, you may be manipulated by people with defined Emotional Center and always devote more than you want. Once you reach a typical point, there is a chance for you to break all relationships. You don’t have to analyse your emotions, just have to understand your feelings are always come from other people. Remember to reserve alone time for yourself.
