Based on the text, who was Ratanji and what was the specific reason for his profound unhappiness despite having great wealth?

Chapter 14 introduces Ratanji as a famous, religious, and very popular Parsi merchant from Nizam's state. He possessed vast wealth, including property, fields, farms, carriages, and horses, and was known for his open-handed generosity. Despite this outward picture of prosperity and joy, he was deeply unhappy. The text explicitly states that the source of his sorrow was that he was without a son. While he had a large family of twelve daughters, the narrative emphasizes that the "happiness of wealth is entirely fruitless for one without a son." This lack of a male heir to support his lineage was the central worry that consumed him day and night, as described in chapter 14.
