How does Chapter 28 contrast the role of a biological father with that of a spiritual Guru?

Chapter 28 draws a profound distinction between a father and a Guru. It posits that a father's role is to give birth to the physical body, an act that initiates a life destined to end in death. The Guru, however, offers something far greater. The text describes the Guru's compassion as "additional" because the Guru works to remove the entire cycle of both birth and death for the disciple. This highlights the Guru's function as a spiritual liberator who frees the soul from worldly bondage, a service that transcends the physical realm.
