Sure, well, we have to wonder if love and hate are correct polar opposites.
Sadness, Sorrow. That's opposite of love.
Anger, or rage, that's the opposite of bliss, and joy, or ardenaline.
Anger is what happens when your tank is empty and you lack all those sweet neuro receptors to smoothly move your way around.
Think of it as exercise. When you are exercising and it feels right, that's joy, happiness, whatever.
When you burn or hurt your muscles, that's anger.
Love is something probably very different. I think sorrow is the opposite of love. Not anger.
Anger is a deficiency, or a lack of capacity for love as opposed to the absense of love?
Unsure, I could slip and slide with this all day.
