I believe that the basic nature of human beings is gentle and compassionate. It is therefore in our own interest to encourage that nature, to make it live within us, to leave room for it to develop. If on the contrary we use violence, it is as if we voluntarily obstruct the positive side of human nature and prevent its evolution.
Interdependence is a fundamental law of nature. Even tiny insects survive by mutual cooperation based on innate recognition of their interconnectedness. It is because our own human existence is so dependent on the help of others that our need for love lies at the very foundation of our existence. Therefore we need a genuine sense of responsibility and a sincere concern for the welfare of others.
There is a common perception that compassion is, if not actually an impediment, at least irrelevant to professional life. Personally, I would argue that not only is it relevant, but that when compassion is lacking, our activities are in danger of becoming destructive. This is because when we ignore the question of the impact our actions have on others' well-being, inevitably we end up hurting them.
Once we have a firm practice of compassion our state of mind becomes stronger which leads to inner peace, giving rise to self-confidence, which reduces fear. This makes for constructive members of the community. Self-centredness on the other hand leads to distance, suspicion, mistrust and loneliness, with unhappiness as the result.
Forgiveness doesn't mean forget what happened. If something is serious and it is necessary to take counter-measures, you have to take counter-measures.
