Hi dECLAN,
Great question I've been thinking the very same thing recently.
What I have noticed for me is that there are times when I can feel anger and am detached; meaning I am aware and can observe it and from this change my perspective on it's origin thus removing the need for anger or from observing letting it subside. This is a very recent practice for me.
I also beleive in experiencing the full range of emotions and sometimes just go with the flow of the emotion but still being mindful of it's consequences and repurcussions, obviously your direction for this emotion is very important. Some may say this is a destructive emotion I would also partly agree with that too.
What I struggle with is when you get hooked by the emotion and are not in a position to observe and detach, that I don't like. Recently there was a situation where I'd had a long day hadn't eaten for over 6 hours and had to deal with several unhelpful people, one situation after another. I got hooked by angry emotions and my blood boiled, not nice for me or them. In retrospect this could be synchronicity at work, my internal emotions and state either attracting or manifesting in the physical world.
