In plain words
This is the chief episode in the story of Hiraṇyakaśipu. So what is called physical science is needed indeed. Through it we must not swell our Ahaṅkāra beyond bounds; recognising that there is so much for everyone to learn, we must try to live in humility and obedience.
Students! In time to come you are the ones to be the country's leaders; all the good and bad of the country rests on your destiny. Only when you are good does the country become good. When you are wicked, the country turns wicked. So all of you must reflect well on this matter of knowledge. When today's students learn a mustard seed of English learning, a pumpkin of ego comes into them. This is the very opposite of what should be. This is not good. We can teach the world many things. Rather than giving these tons and tons of speeches, practise one ounce: that is enough. So in our daily life we must carry on this preaching and teaching in what can be put into practice. In this way the knowledge of Bhārata became the essence of all śāstras, stood as the goal of all learning and became the guiding principle of life.
This whole world is made of just two things. What are they? One is name. The other is form. Apart from name and form, nothing else whatever is to be seen in this world. This name is sound. In this sound the world lies contained. This sound itself is speech. The life of speech is feeling; the life of feeling is desire. The life of desires is ignorance. The life of ignorance is divinity. From what is called divinity, ignorance came forth. So we must bind divinity and speech together in kinship. Without speech we can grasp nothing at all. For everything there is a sound. From sound itself we all came forth; we did not create sound. So from ancient times a meaning has gone on forming for sound. No physical science created this meaning. This is a plate. Who created this plate? A gold smith may make the plate; but who named it? The name has come down from ancient times. This is a tumbler. What is the proof of the tumbler? Its form is its proof; so the proof of a name is its form. The proof of a form is its name.
