In plain words
In both these kinds of education we must recognise the right path. In everything we must carry out a kind of investigation. We must make enquiry. That itself is the work our Buddhi follows.
Having studied every study and grown very wise, the dull-witted one does not know himself in his heart; however much he studies, whatever way he lives, the low man cannot give up his base nature.
Through these studies he cannot recognise his own true nature. These worldly studies have no power or capacity to drive away one's … baseness. Only the power of tapas has the strength to drive it away.
Study searchingly as you will, it is only argument and logic; full Jñāna he can never gain; why study every study only to die? one must study the study that knows no death.
Your money, your time, your energy: you are pouring all of it out on this. Not only this. You are causing your mother and father a great deal of hardship too. Your mother and father go through any number of troubles to educate you. They run into debt to pay for your studies. Though they go through these troubles and run into debt to educate you, in the end you bring them harm in every way. We do not give those parents the joy they deserve.
Students! Above all, when you cannot … the inner meaning in this education, make your mother and father happy. This is the true essence of education. If we cannot give proper satisfaction even to the mother and father who bore us, raised us, brought us up and educated us, how can we ever give it to others? That is why, first of all: mātṛdevo bhava, pitṛdevo bhava, ācāryadevo bhava. Do not keep saying 'God, God'. Do not lean only on a principle you do not know. The principle that is known, that shows itself to the eye, makes itself known to the mind, delights the heart and makes you forget the body: that is the principle of your mother and father. Learn this education that gives satisfaction. Do not go on depending on them for ever. Till now they have reared you and protected you. In their old age you must try to protect them. So these are the studies you must above all pursue. Along with these studies, you must take on certain duties in the worldly, the physical and the natural sphere. … though we keep this spiritual life itself as the chief goal, the worldly too must stay beside it as something essential. That is the positive. If it has no negative, the positive is of no use.
