At the root of virtually all spiritual practices is the notion of forgiveness. This was what came out of Jesus of Nazareth while he was being tortured on a cross by a Roman soldier throwing a spear into his side. It is perhaps the most healing thing that you can do to remove the low energies of resentment and revenge from your life completely.
Think about every single person who has ever harmed you, cheated you, defrauded you, or said unkind things about you. Your experience of them is nothing more than a thought that you carry around with you. These thoughts of resentment, anger, and hatred represent slow, debilitating energies that will disempower you. If you could release them, you would know more peace.
You practice forgiveness for two reasons. One is to let others know that you no longer wish to be in a state of hostility with that person; and two, to free yourself from the self-defeating energy of resentment. Resentment is like venom that continues to pour through your system, doing its poisonous damage long after being bitten by the snake. It’s not the bite that kills you; it’s the venom. You can remove venom by making a decision to let go of resentments. Send love in some form to those you feel have wronged you and notice how much better you feel, how much more peace you have. It was one act of profound forgiveness toward my own father, whom I never saw or talked to, that turned my life around from one of ordinary awareness, to one of higher consciousness, achievement, and success beyond anything I had ever dared to imagine.
Indeed, there are no justified resentments if you wish to walk along the extra mile and enjoy inner peace and success on every step of the path.
