Can you explain the paradox of Ratanji's situation, described as outwardly joyful but inwardly worried, and what it reveals about human happiness?

The paradox of Ratanji's life, as detailed in Chapter 14, is that while he was "outwardly swimming in an ocean of joy day and night" due to his immense wealth, he was simultaneously tormented by the "crocodile of a difficult inner worry." This contradiction reveals a profound truth about human happiness: it is not guaranteed by external circumstances. The text explicitly states, "no one has unmixed happiness. Everyone has some nagging worry or the other behind them." Ratanji's story serves as an example of this divine plan. Despite his charity and pleasant demeanor, his lack of a son made his worldly happiness feel "entirely fruitless," showing that inner peace and fulfillment are separate from, and often more important than, material prosperity.
