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

Ratanji was a famously wealthy, religious, and generous Parsi merchant from Nizam's state. As described in Chapter 14, he possessed vast properties and was known for his charity. However, despite his outward prosperity, he was tormented by a deep inner worry. The source of his profound sadness was that he did not have a son to continue his lineage. He had twelve daughters, and the text notes that for someone without a son, the happiness derived from wealth is considered fruitless. This constant desire for a virtuous son was a daily contemplation that left his mind in a state of perpetual unrest and sorrow.
