Thoughts of revenge create an energy of imbalance and is best dealt with by releasing your anger.
There can be times when we get so angry with someone that we find ourselves imagining ways to seek revenge for the hurt they've caused us. Remember, however, that the thoughts you've just had are energetic creations. In order to keep yourself from having to take part in the rebalancing of energy, it is important to release the person and the thoughts into the care of the universe with forgiveness. 

Before we allow ourselves to invest our energy into negative thought or action, we can remind ourselves that everything has a purpose. We can then consider that perhaps the actions of the other person or people may have had nothing to do with us. If we don't take their actions personally, it may be easier to release them. Remembering that every interaction is an opportunity to make a better choice, we can take a deep breath before responding, allowing us just enough time to connect to center and make the choice to respond from our higher self. We can never know all the circumstances that may have led anyone to do anything. By not passing judgment on anyone, and instead sending hope for their healing, we may create something positive out of a difficult situation. We can then release it, since dwelling on it can cause an energetic drain in our system, causing us to really only hurt ourselves. When we can release our hold on negative events and interactions, we leave it in the hands of a wise universe to work out the best solution for all involved. 

In every moment we have a chance to make a choice to bring light into the world. When we bless others with the gift of our positive energy, instead of letting circumstances affect us negatively, we bring a little peace to the world every day.
