How does Ratanji's story illustrate the book's philosophy on happiness and worldly success?

The story of Ratanji in Chapter 14 serves as a parable on the nature of happiness. Despite being a man who was "swimming in an ocean of joy day and night" from a worldly perspective, with vast wealth and property, he was tormented by an inner worry. The narrative explicitly states, "this is the divine plan; no one has unmixed happiness." His story demonstrates that material prosperity is meaningless without inner peace and the fulfillment of one's deepest desires. The text compares a household without a son to a pilgrimage without repentance, emphasizing that true contentment is not guaranteed by riches but is a matter of spiritual fulfillment and divine grace.
