In plain words
So science and technology are indeed sacred. They are indeed useful. They do indeed increase man's cleverness greatly. Using the power of the intellect, they can indeed do the country any amount of good. But such a pure, industrial principle, when it reaches a man's heart, takes on the very form of whatever kind of heart that man has.
So you must become pure of heart. You must become clean of heart. You must become people whose hearts are set on the Supreme. You must become people whose hearts are set on Dharma. That itself is the chief excellence of education. Today the principle of Prema is not seen at all. It must be a Prema from heart to heart. Prema is God. God is Prema. Only in a heart that has such selfless Prema does the Paramātma shine. Though the Paramātma is in the heart of all, daivaṃ mānuṣa rūpeṇa: we must try to recognise well this divinity in human form. We must gain the strength to make manifest the divinity that lies unmanifest in us. So we must believe well in our ancient traditions, practise them and receive their Ānanda.
Today a great deal of unrest has grown up in society. Discontent has grown up still more. What is the reason? Selfishness and self-interest have gone beyond all bounds. We must root out this selfishness and self-interest. This is to be had by us only on a spiritual path, on no other path. Only when we put the seed in the earth and tend it does it change into a tree and give fruit. Put it in a tin and pour water on it, and that seed rots. In just the same way, the principle of Prema today can grow only on a spiritual path; it cannot on any other path.
Study. Study. Study. Study there must be. Along with it there must be saṃskāra too. It is only through study without saṃskāra that the whole country today is turning into such turmoil. Humanity itself has perished. This is nothing but the fault of having no saṃskāra. Saṃskāra we must receive through our parents alone. So parents must bring up their children in the right way. They think, 'Our responsibility is over the moment we have put them in an educational institution.' The responsibility of shaping them into good citizens is the parents'. But they do not take this much care. That is why the children are going astray. We must sow sacred seeds in their hearts, spiritually. Without that, humanity does not flourish at all. Śaṅkarācārya, Vivekānanda, Gāndhī and all other such ideal men: it was only by being people of saṃskāra that their parents became the root cause of their growth.
