Anger is such a terrifying emotion. Every now and then I become aware of feeling furious about something. It may be triggered by a seemingly inconsequential event such as an interaction with a rude customer service person, or more seriously by a random act of cruelty. Those reactive flashes of engagement with the world are still manageable, although unpleasant.
Sometimes, however, the thing that happens resonates at the core level of myself, reminding of a violation that occurred before I could fend for myself. And then, with the surge of a volcanic eruption, I become subsumed by the primitive ferocity of a threatened wild animal, and I pity those who stand in my way. It is only later that I understand the dislocation in time and space, but by then the damage is done.
