Wrath of pious people, which is an outrage against the sin, is considered righteous, and anger against your fellowman, especially dragged, is considered sinful. Wrath includes irritability and the intention to bring evil. The man who is easily irritated, is constantly endangered to commit badly, causing the incorrigible harm to himself and others.
Wrath and taking offense are double-edged weapons, and in the first place, they are aimed at us, but not our offenders. Resentful people punish themselves hard, sometimes reaching complete exhaustion. State of anger is a very strong stress. Therefore, the ability to forgive one's enemies and offenders is greatly useful for one's spiritual, as well as mental and physical health.
Wrath is an absolute opposition and denial of love. It not only brings upon conflicts, but also demolishes feelings of love, friendship, sympathy and respect that we have for people. A minute of wrath changes our attitude to the person; his features and traits that might have caused our admiration, now appear distorted, ugly, and grotesque.
Self-conceit, self-love, and exaggerated self-esteem Ц these are the most common reasons for taking offense and wrath. Another one is being envious of others' possessions or achievements.
Kindness means seeking to do good to others, understanding, and sincerity. Kindness makes us tolerant, willing to help, able to care and love.
Kindness is opposite to wrath. The latter comes from the weakness of the soul, and the first - from its strength. "Wrath is born because an obstacle makes the soul save its physical strength, which at present it is lacking, to be on a level with this obstacle, while kind feelings are reborn owing to opposite factors: it happens when the soul feels that it has got more strength than necessary at the moment. This excess is reflected in the soul with the feelings of kindness, affection and tenderness, which, just in the same manner as wrath, tend to get individualized, focused on some concrete object and pour themselves on it.", - L. Ushinsky. Thus, it is only the spiritually rich and strong person that can be kind.
The feeling of kindness differs from the feeling of love. Love often forces us to be cruel to what we love and sacrifice it to our pleasures; but kindness encourages us to be good, not only to what we love, but to all creation, and often - even to what we hate or despise.
