Like justness in a judge's decision, or beauty in a painting, soul is a quality of absoluteness in something relative. Understood profoundly, people are connected to the holiness of the world in such a way that they reveal a dimension of holiness in themselves, a dimension of depth that is absolute.
It would be far more constructive if people tried to understand their supposed enemies. Learning to forgive is much more useful than merely picking up a "stone" and throwing it at the object of one's anger, the more so when the provocation is extreme. For it is under the greatest adversity that there exists the greatest potential for doing good, both for oneself and others.
