Deep wounds are typically the root… (often leading to childhood wounds) your gateway emotion is like the immediate emotional response.. like a trigger..
You can do a root cause analysis in a sense. For example, let’s say you were raised by a parent who’s love is conditional. That may later cause you to feel as though you’re not doing enough to earn a partners love later. Or that you have to “do” in order to receive love. So the root is the childhood wound that you were taught love is conditional and then you can replay how that has affected your behaviors in relationships and self-worth. It’s deep work, also known as shadow work.
Does that make sense?
