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

Chapter 14 describes Ratanji as a famous, religious, and popular Parsi merchant who possessed vast wealth, including property, carriages, horses, and farms. He was known for his generosity and pleasant nature. However, despite being seen by the world as swimming in an "ocean of joy," Ratanji was tormented by a deep inner worry. The source of his constant sadness was that he did not have a son. The text states that he had twelve daughters in a row, and this lack of a male heir made his immense wealth feel "entirely fruitless." This contemplation for a virtuous son left his mind in a state of perpetual unrest, making him sad and unable to enjoy his life.
