How does Chapter 50 differentiate the role of a Sadguru from that of a worldly father?

According to Chapter 50 of the Shri Sai Satcharitra, a worldly father is the progenitor who gives physical birth, a role that one encounters in millions of births. In contrast, the Sadguru is described as an 'extraordinary progenitor' who provides a spiritual rebirth. This chapter explains that the Sadguru gives birth to his disciple through full initiation (Anugraha) without any physical process. While a worldly father gives a body, the Sadguru is revered as the one who can end the cycle of birth and death, making him the true, merciful father who saves his devotees.
