How does Chapter 28 distinguish the role of a Guru from that of a biological father, and what are the purifying effects of hearing stories about saints?

Chapter 28 draws a clear distinction between the roles of a father and a Guru. It posits that a father gives birth to the physical body, which is inherently tied to the cycle of birth and death. In contrast, the Guru's compassion is described as "additional" and far greater, as the Guru works to remove the disciple from this entire cycle. The chapter also highlights the spiritual benefits of sacred narratives, stating that listening to the stories of saints is "supremely purifying" and has the power to destroy sins, including those acquired from hearing slander and false stories.
