In the olden days, people taught their children the truth of what is permanent and what is fleeting. They taught them that the aim of life is God realization. The children were given an education that enabled them to understand who they were. Nowadays parents encourage their children only to earn money. What is the result? The child doesn't know the parent and the parent doesn't know the child. There is enmity and fighting between them. They may even kill each other for selfish reasons.
