Based on the text, can you provide a character analysis of Ratanji, highlighting his virtues and his main internal conflict?

Ratanji was a famous, religious, and popular Parsi merchant from Nizam's state. He was characterized by his immense wealth and profound generosity, with the doors of his mansions always open to help others. Chapter 14 notes that he was always pleasant and actively worked to remove the poverty of the downtrodden. However, his main internal conflict was the deep-seated sorrow of not having a son. While outwardly appearing to be 'swimming in an ocean of joy,' the text describes this lack of a male heir as a 'crocodile of a difficult inner worry,' making his worldly happiness feel entirely fruitless.
