In plain words
The power that weighs and decides what importance is to be given to which object, in what place, at what time and in what way: that very power is called vijñata. This vijñata is a part within Viveka itself. One without Viveka and discernment cannot enter the good path. Every person who hopes to lead a life on the good path must try to live with Viveka and knowledge. Learning without Viveka has shown no discernment at all. Einstein once said: Knowledge that cannot accomplish action is useless. Action without knowledge is foolishness. Our knowledge must be such as accomplishes action. It must be action joined with knowledge. Today knowledge that cannot accomplish action, and action that cannot use knowledge, they use only for a name, only for fame, but they are not trying to recognise the special worth of human nature. However rich, however learned, however educated a man of knowledge may be, if he is without human feeling society will not honour him. A person with such power and ability cannot win the regard of the people. Through the powers of atomic research we can invent deadly weapons that turn the whole universe to ash in a moment. Through that same atomic research we can develop some crores of units of electric power, through them develop industry and agriculture, and make the country green with crops. Not only this: we can give work to crores of people. For every man to use in society such Viveka as does good to the world: that alone is the supreme aim of this knowledge. Only when this Viveka knowledge is used for the welfare of the world and for holding the world together does it take shape as right learning. Otherwise, learning that brings turmoil and utter ruin to the world takes on the nature of one that has merely followed a perverse path. The world condemns the nature of such people too. It reviles people who misuse power in this way as thorns in the world's side. Truly, the learning we have gained must take the shape of something that brings fitting cooperation, help and good to our society and to our fellow man. It must foster unselfishness and concern for others, and show forth its true form. Along with śāstra knowledge we must show forth experiential knowledge, and along with experiential knowledge, Viveka knowledge.
A person who has gained the knowledge in which these three are blended can easily understand the qualities and nature of people, whether they are before him or far away. A man without experiential knowledge, knowledge and discernment becomes a blind man who cannot recognise the pure heart that is beside him. The bee, though it is far away, recognises the scent of the nectar in the lotus flower, comes straight to the lotus, alights on it, and enjoys that nectar, that sweetness.
