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

Ratanji was a famously religious and wealthy Parsi merchant from Nizam's state. As described in Chapter 14, he possessed vast property and was known for his generosity, yet he was deeply troubled. While he seemed to be "swimming in an ocean of joy," he was plagued by what the text calls a "crocodile of a difficult inner worry." This profound sadness stemmed from the fact that he had no son to carry on his lineage, having had twelve daughters. The narrative emphasizes that for someone without a son, the happiness derived from wealth is considered "entirely fruitless." This constant worry for a male heir meant his mind was never at peace.
