You will only arrive at what you are aiming to achieve through the cultivation of two fundamental attitudes of soul. You must nurture a true love for what you represent, and also an insightful love of humanity. Be quite clear that if these two conditions are not met, you may be able to present material ever so logically, you may be able to demonstrate exceptional cleverness, and you will still not achieve anything.
Forgiveness means accepting the core of every human being as the same as yourself and giving them the gift of not judging them. You can be clear about whether or not a person's behavior is acceptable without judging the person. Forgiveness starts with ourselves and extends to others. Accepting that the core of your own being is as precious and wonderful as that of any other person is the greatest gift you can ever give yourself.
