In plain words
I hope that you will build this kind of firmness in your heart, and through it bring about real changes in your own conduct from now on, then bring about a change in turn in those who are your companions, and through them shape once more, all over again, the high state of Bhārata.
Another small example. There is a broken-down old car at our house. It is a car in no kind of condition at all. When we make a plan to fix it up, have proper parts fitted, rid ourselves of the nuisance and foist it on someone's head, we take it and leave it at the workshop. When it is of no use of any kind, the car is in a state where it is no good even for the children to sit in and play in our compound. Once such a thing is put in the workshop, because many kinds of new parts are fitted here, someone or other sees it as something of value, is drawn to it, and sets about taking it away. If instead we tie this car from our house to some lorry or some car, take it to the workshop, then tie it again from the workshop to some car or lorry and bring it back to our house, what is the car worth? Before this, knowingly or unknowingly, you may have let some parts work loose, let some kinds of bolts and nuts work loose, and may be like people of no use in any way. Not all of you, though; some. But because it has come to the workshop called satsaṅga, the summer class, only when it takes on new bolts and new nuts here and goes away in good order is there any kind of chance for someone to say it has come out a proper car and give it a fine value, and for it to draw another's eye too. If instead you go out of this workshop in the very condition you came in from there, there will be no value at all. Before, the car used to stand in front of the house. Now they push it round to the back of the house and throw a tarpaulin over it.
