Can you explain the nature of Ratanji's inner turmoil and what it teaches about the sources of human suffering?

Ratanji's inner turmoil, as described in Chapter 14, stemmed from his lack of a son despite having immense wealth and twelve daughters. His suffering teaches that happiness is not guaranteed by material possessions. The text compares his situation to fruitless endeavors, such as "Hari-kirtan without love" or a "household without a son," highlighting that worldly success feels empty without a specific, deeply desired fulfillment. His constant contemplation was, "Will Narayan give at least one virtuous son?" This worry made him perpetually sad, unable to enjoy his food or find peace, showing that suffering often arises from a perceived lack that external prosperity cannot satisfy.
