Anger brings out truest self. When I am truly angry, deep-down angry to the core, I am truest to my pure self. I am not entwined with the compunction to please, and in such, conforming to what I perceive others to want or need. I am me, take me or leave me. The 'other' an actual equal standing before me. Me and you. Here and now. How intense is that? An actual life force equal to yourself standing before you! Stripped bare by your own intensity of here and now! As purely God-made as you, here and now. And who are you?
Anger is the purest and most purefying of the emotions. It is imediate and uncompromising. It cuts through al the crap. Anger takes no for a challenge. Anger takes on all comers. Anger simmers and restrains with logic. I distinguish anger from rage. Rage has no boundaries, anger is weighed and meditated. Anger is not hate. Anger is righteous and and meted. Anger heeds the call of necessity. Our anger is our identity, our uncompromisingly truest identity manifest in the absolute moment.
Emotion is what makes us more than human. Emotion is what separates our existance from that of the chair. Without emotion we leave as much behind our oh-so important lives as the chair.
If we fail to recognise the state of grace that ovewhelming emotion truly is, our being will wither away behind the barrage of others' emotional imposition and render us nowhere on the map of human existance.
Our emotions are our humanity. They are our strength. They cut a wedge in the pie of life for us to own, and stand within, and be recognised as a legitimate part thereof. Without emotion and the conviction it brings, we are inconsequential. We are at our best when we ride their current and trust our own selves and stand fierce in our conviction and demand to know, "who are you?" and "who are you to question me?"
I hope I've responded to what you were asking, and was helpful.
