The indifference, callousness and contempt that so many people exhibit toward animals is evil first because it results in great suffering in animals, and second because it results in an incalculably great impoverishment of the human spirit.
Those who have compassion when they do battle will be victorious. Those who likewise defend themselves will be safe. Heaven will rescue and protect them with compassion.
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.
Be a good human being, a warm-hearted affectionate person. That is my fundamental belief. Having a sense of caring, a feeling of compassion will bring happiness of peace of mind to oneself and automatically create a positive atmosphere.
Rage is a powerful energy that with diligent practice can be transformed into fierce compassion. However much we disagree with our enemies, our task is to identify with them. They too feel justified in their point of view.
What is the relationship between spirituality and ethical practice? Since love and compassion and similar qualities all, by definition, presume some level of concern for others' well-being, they presume ethical restraint. We cannot be loving and compassionate unless at the same time we curb our own harmful impulses and desires.
