In plain words
Teachers come to be fathers too. To become a father is no great thing. One must be an ideal father. That is what matters. Teachers who cannot keep even their own children as they should, how then can they set students right? The teachers themselves are letting their own children's conduct go wrong.
Praising and praising their children whatever they do, fathers are turning into Dhṛtarāṣṭras where their children are concerned. You may praise what is good. But you must rebuke what is bad. Raising them like that, in blind love for the son in everything, gives the sons room to stray a little onto a wrong path. So fathers must not be fathers like Dhṛtarāṣṭra. Not only that. To students who conduct themselves with fine Bhakti and surrender, with humility and obedience, only this: ‘What is this, boy! Why this Bhakti at so young an age? You can do it near God after retirement’: there are fathers too who teach them so. Fathers must not be like Hiraṇyakaśipu, breaking all these students' Bhakti and surrender to pieces.
Students must be the kind who give ideals to others. They must take the command of mother and father on their head, but where something is at fault, they must explain it to them well, with humility and obedience. Then they too will be glad. Not all parents are like that. Many are good. Because one or two children change in this way, the other children, seeing them, change too.
What is education? Mere acquaintance with books is not education. What teaches many meanings for words is not education. Education is what opens the doors of the heart. Education is what brings breadth of heart. Education is what brings control of the senses. Education is what seeks the good of the world. Education is what fosters every good quality. What is an education without such qualities for? What is the reason for losing these qualities and control of the senses? Too much talk. Through this very excess of speech a man loses his memory power. He loses the power to examine what is lasting and what is passing. He loses the discernment of how to conduct himself before elders. On this, research has been done in many places in the world.
In Columbia he built up a primary school. For some twenty-five years he went on doing research among the students. Walter Mitchell was his name. He carried out research on all the children. He would seat ten children at a time under each tree.
