If a person is sensitive, he will not do to someone that which he would not want another to do to him.
Why does a person commit a crime? This is because he is insensitive and some where he has lost touch of his humaneness. He has become like a beast. But that beast-hood is not a permanent thing. That is why I say, inside every culprit there is a victim crying for help. If you heal the victim, the culprit in him disappears.
That is where inner awakening or spiritual elevation or lifting of the consciousness to a higher level is absolutely essential. It is not just enough to make our children computer-wizards. We need to implant in them human values.
Our youth should feel for others, they should shun violence. And when can they shun violence? When they are free from stress. If they are stressed, they become violent.
There are two reasons for violence: one is stress and the other is ignorance or wrong indoctrination.
