What philosophical ideas about happiness and fulfillment are presented in Chapter 14 through Ratanji's story?

Chapter 14 uses Ratanji's story to explore the nature of happiness and fulfillment. It begins by establishing a key philosophical point: "no one has unmixed happiness. Everyone has some nagging worry or the other behind them." Ratanji's situation, where immense wealth fails to bring him peace, illustrates that material prosperity is insufficient for true contentment. The text deems his wealth "entirely fruitless" without a son, comparing his situation to beautiful things that lack an essential quality, such as a "pilgrimage without repentance" or "Hari-kirtan without love." Ultimately, as Chapter 14 narrates, the path to fulfillment is shown to lie in spiritual surrender, as Ratanji is guided to seek a divine solution from Sai Baba, whose power is described as "inconceivable."
