The book mentions a wealthy Parsi merchant. Can you tell me who he was and explain why he was so unhappy despite his immense riches?

The text introduces a famous, religious, and popular Parsi merchant from Nizam's state named Ratanji. He possessed vast wealth, including property, carriages, and farms, and was known for his generosity. However, as Chapter 14 explains, while he was outwardly 'swimming in an ocean of joy,' he was tormented by a deep inner sorrow. This unhappiness stemmed from the fact that he had no son. He had a large family of twelve daughters, but the absence of a male heir made his worldly happiness feel 'entirely fruitless' and left his mind without peace.
