Who was Ratanji and what was the source of his deep unhappiness despite his immense wealth?

Ratanji was a very religious and popular Parsi merchant from Nizam's state, known for his vast wealth, property, and generosity. As described in Chapter 14, while he was outwardly 'swimming in an ocean of joy,' he was internally tormented by a significant worry. The source of his unhappiness was that he had no son to carry on his lineage, despite having twelve daughters. The text poignantly states that for someone without a son, the happiness derived from wealth is entirely fruitless, and this constant worry left his mind with no peace.
