Besides animals, what other comparisons does Chapter 8 use to illustrate a life without higher purpose?

To emphasize the need for a higher spiritual purpose, Chapter 8 of the Sai Satcharitra uses comparisons beyond just animals. The text asks what trees lack if the only goal is to have a body, implying that mere existence is not enough. It then makes a more unusual comparison, stating that even a blacksmith's bellows breathes, but this mechanical action is not equivalent to a meaningful life. These analogies, found within Chapter 8, serve to highlight the idea that physical functions like breathing or having a sturdy body are insufficient and that the true success of human birth is the realization of the Eternal.
