I don't know how this doesn't have more comments because that last paragraph had me shook, that is so true. There is something primordial about that feeling connected to these words. It's so strange that a work can evoke such a feeling, it's like the nicotine hit after a drag on a cigarette. That line 'Word heat', is that your phrase? It perfectly describes the affectivity of certain words on evoking an emotional response.

It's strange how we reuse a lot of the same emotional pathways between family and loved ones.
