Why is man given a better life than that of the Pig?
Why is a highly placed government servant given better facilities than those of an ordinary clerk? The answer is that a highly placed officer has to discharge duties of a higher nature. Similarly, the duties human beings have to perform are higher than those of animals, who are always engaged in simply feeding their hungry stomachs. Yet the modern soul-killing civilization has only increased the problems of the hungry stomach. When we approach a polished animal in the form of a modern civilized man and ask him to take interest in self-realization, he will say that he simply wants to work to satisfy his stomach and that there is no need of self-realization for a hungry man.
