According to the text, what is the difference between a father and a Guru, and how does this relate to Sai Baba's role?

Chapter 28 draws a profound distinction between the role of a biological father and a spiritual Guru. The text explains that a father gives birth to the physical body, which is inevitably subject to death. In contrast, the Guru's compassion is described as "additional" because he removes the very cycle of birth and death for the disciple. This highlights the Sadguru's role in providing ultimate liberation, which transcends the physical realm. Sai Baba embodies this role by not just caring for his devotees' worldly needs but by guiding them towards spiritual freedom from the bondage of karma, as elaborated upon in this chapter.
