Any force in which you experience, or energies encountered; can be used as fuel for other purposes. Remember your purposes are valid and, yet, yours alone. Often times we simply banish anger to the recesses of our hearts. Damning her for being so destructive. But you can keep her, in a place of honor. And then with the honesty of the original flame of such anger you can transform her into whatever you desire. But you must have the same conviction for the anger as you do for her new state of being.
