In plain words
In our ancient scriptures there are many precious matters. Valuable gems lie hidden there; technical secrets of atomic theory, too, are found in abundance. The search for them must be begun, and made useful for human progress. In every student, the zeal to discover new matters and the perseverance for it must, without fail, be present. One must not be content merely with giving grand lectures or with adorning debate platforms; the eager curiosity that says, 'One must conduct inquiry and discover new matters,' must be present. Only such people can give knowledge to the world. Superficial knowledge yields no benefit; there is no knowledge greater than experiential knowledge — none other exists. Therefore, such experiential knowledge must be attained by one's own strength, one's own motivation and one's own effort, with perseverance and diligence, and used to help technical progress, to increase production, and to serve the nation's progress.
Just as it is necessary to acquire experiential knowledge, it is equally necessary to have the discerning knowledge that puts it to use for good and for the nation's welfare. Learning without discrimination, and knowledge that cannot show judgment, yield no benefit whatsoever. Discrimination is one thing; learning is another. Knowing the difference between good and bad is precisely what marks discrimination. Having recognized such a difference, the power and ability to determine how much, when, and what kind of importance to give it is what they call 'vichakṣaṇā-jñānam.'
Vichakṣaṇā-jñānam is an inner part of discerning knowledge; one who lacks discrimination cannot grasp the right path. Displaying discrimination in every task we perform is the mark of good sense. By conducting atomic research, one can manufacture, in a single moment, weapons of destruction capable of reducing the world to ashes; by that very same atomic power, one can also manufacture electric power worth several crore kilowatts of strength. Adapting it for industries and agriculture, the nation
