When acts of cruelty, verbal or physical, are bestowed onto you or someone that you love, it is extremely difficult to see that the one inflicting cruelty is actually hurt inside. But, as a civilized race, accountability must be put into place.
Accountability can be karmic. When someone consistently hurts others they are living, breathing and acting within a certain frequency or energy vibration that inevitably draws others of that same frequency to them. The very thing they bestowed upon others will soon be given to them in a similar form. This is the law of cause and effect. It is the natural law of the Universe. What we put out into the world, is what comes back to us.
I have found, the quicker I let the cruel incident go, the sooner I rise above it, meaning, I wipe away the tears, look past it and focus on being the best and most loving person I can be with discernment. Discernment is important. Choosing to be around others who bestow kindness and love and distancing yourself from those that are harsh and unkind will only empower you and your life.
