Ratanji of Nanded was described as having 'vast wealth and property' and yet was deeply unhappy. Can you explain the source of his sorrow and what it teaches us about happiness?

According to Chapter 14, Ratanji was a very wealthy and generous Parsi merchant from Nanded who outwardly seemed to be 'swimming in an ocean of joy.' However, he was tormented by a deep inner worry. The source of his sorrow was that he did not have a son, despite having twelve daughters. This desire for a male heir consumed him to the point that food and drink no longer tasted sweet and he was in constant distress. The text uses his predicament to teach a lesson that no one has 'unmixed happiness' and that external prosperity does not guarantee internal contentment. Ratanji's story shows that happiness is subjective and that even immense wealth can feel 'entirely fruitless' when a deep-seated personal desire remains unfulfilled.
