In plain words
A doctor who has studied for the M.B.B.S may understand nothing at all of an engineer's work. He may develop his intelligence only in his own learning. In another field his intelligence is of no use at all. In the same way, the limit of the physical scientist's faith cannot be compared with spiritual faith. That is a very petty state. Is it possible for such people to grasp a principle that is higher? A small example. This is the modern age. An age in which technology has flourished. At this time, when we take certain examples, we come to believe this. In Delhi, a man at the Ākāśavāṇī broadcasts his words and songs. While this man is singing in Delhi, some lakhs of people sit in their own homes and listen to it through the radio. When the song is sung in Delhi, we listen to it in our home, held to its śruti, laya, rāga and tāla. There is no change at all. In the same way, someone in Delhi is speaking on television. Though that person is far from us, we watch him in our home on our T.V. Many crores of people watch too, just as we do. The songs sung in Delhi, the man speaking in Delhi, people can hear and see in every home just as in ours. How are they able to hear the same man, the same words, in different places at one and the same time? How are they able to see him? Ask this, and many kinds of scientific answers come forward. So too, in that age, Gopāla Kṛṣṇa gave darśan in the homes of sixteen thousand Gopīs at one and the same time. When they say they were able to see Him at one and the same time, the questions about it are many. How can this happen? Some kinds of criticism ask, ‘Is this possible?’
As for these people who believe today that the power of mantra has no power of any kind, how did the power of machines come to have it? When the power of a machine alone holds so much power, why should it not be in the power of mantra? Besides this, as fools who cannot grasp its inner meaning, they criticise it. How do the sound waves in that Ākāśavāṇī come here to us? All these sound waves merge into the waves of electric power, and all these waves of electric power, transient as they are, turn eternal; all these impermanent waves take on a permanent form and go on travelling everywhere in what is called ether. Today, now that we know the radio, we are able to say today that we hear in Prasanthi Nilayam the songs that are in Delhi; but even in those days these sound waves lay merged in these waves of electric power.
