The student has to unfold a wider sense. He must begin to see the whole of which he forms a part, which means he must become more philosophical. His physical existence depends on the services of others, from the parents who rear him, the wife who mates him, the customer who buys his goods or services, the farmer who grows his food, the soldier who guards his country, to the undertaker who buries his body. No man can forever isolate himself from the rest of mankind. In some way or other, for one essential need or another, he will come to depend on it. The shoes he wears or the food he eats were prepared for him by somebody else. Thus he is mysteriously chained to his human kith and kin. Thus he is forced to learn the lesson of unity and compassion.
