How does Chapter 50 describe the unique role of a Sadguru compared to a worldly father?

According to Chapter 50 of the Shri Sai Satcharitra, the role of a Sadguru is portrayed as profoundly different and more extraordinary than that of a worldly father. While a worldly father gives physical birth through the womb, the Sadguru is described as a unique progenitor who gives a spiritual birth to the disciple. This chapter explains that the Sadguru does this without the physical act of procreation, granting full initiation or 'Anugraha.' This spiritual rebirth, given by the 'remover of birth and death,' is considered the path to ending the endless cycle of reincarnation, making the Sadguru's role paramount for spiritual salvation.
