Do not act upon thy aggression if thou are not satisfied with what you have. If you still envy others and want to possess what is theirs, work hard to rid yourself of that aggressive feeling in your heart. Do not abuse that moral asset. Aggression is a fragile inborn nature in man and has to be applied by civil means.
It is your moral obligation to rid yourself of all covetous feelings. If they still remain in your desires, it is your duty to get rid of them. Look into your inner self and find the way to do it. When you find it, all your aggressive feelings will be morally right. Civilization depends upon you to do so. Be a good citizen. Please.
