When we've put in this work, we develop a solid sense of self: we know where we end and where others begin. We stop picking up energy, trauma, and problems that we cannot resolve (we can move through our own trauma: feel it, find its roots, and break it down. We can't do that with that of another, because we will never know the full story). We mind our own business, so to speak, and we step into a powerful experience.
We are not at the mercy of others’ powerful emotions. Not always easy, especially not in emotionally-charged situations, but becomes easier with work over time.
The best way I’ve gotten familiar with these delineations is by tuning in and making sure I’m accurately describing the granular aspects of my emotions: not just sad, but despondent, or heartbroken, or disappointed. Not just angry, but confused, or irritated, or downright irate.
There are layers to ourselves, and the sooner we know where we are and that to which we aspire, the sooner we can maintain our vibe in the face of whatever is to come.
