I also learned from my childhood the Vengeance is sweet. The women in my family most definitely believed in revenge. Whether it was cold silence, icy glares, destruction of physical property, eye for an eye, withholding affection, or worse..it was the way I learned to let someone know when I'm displeased with their actions.
To me there is no difference between one person and another; I behold all as soul-reflections of the one God. I can't think of anyone as a stranger, for I know that we are all part of the One Spirit. When you experience the true meaning of religion, which is to know God, you will realize that He is your Self, and that He exists equally and impartially in all beings. Then you will be able to love others as your own Self."
