When you've been screwed severely all your life and you have pent-up aggression inside up to the brim within - understand, it's going to DESTROY you if you don't release it. Its harmful, destructive power is not meant to stay in your psyche; you must direct it at someone or something - preferably both!
Rage is unadulterated anger in its purest form and extraordinarily potent and lethal when directed towards a target. Only when you channel it completely are you at peace and feel like an angel again. That is the nature of a dual soul - one married to darkness but born in the light. Your anger is not the bad guy. It is in you to balance you in this cruel world and know complete composure and stability, no matter what you go through. And that is something not many people can do - marry their darkness.
Embrace your wrath - it will heal you!
