I think what you are talking about reflects the concept of centeredness…When we may be experiencing trouble and trauma in the physical sense but not inwardly.
When circumstances arise that would normally generate fear or even panic, and we respond with acknowledgment, not blocking or denying that fear. Not attempting to control emotion, circumstances, or other people. Then moving toward peace as we process the emotion and circumstance. That inner tranquility acknowledges that being ok on the physical level is much more than a setting of physical things.
Likewise when relationships disturb us, we move from acknowledgment, processing, to the reality that no matter what happens we are still where we should be, learning what there is to learn, growing because of the “disturbance” and being thankful for it.
Gratitude in crisis is what I would call emotional mastery. As we experience and process the emotions, we may not “Look” or “feel” very mastered. Emotions will move. But the process moves us to a place more peaceful and we grow in wisdom.
Just knowing that as we experience this is emotional mastery and inner peace. It will come out “right” in the end.
