How does Chapter 50 of the Shri Sai Satcharitra explain the significance of a Sadguru compared to a worldly father?

Chapter 50 draws a profound distinction between a worldly father and a Sadguru. While a worldly father gives physical birth, placing a seed in the womb, the Sadguru is described as an extraordinary progenitor who provides a spiritual rebirth. As detailed in the chapter, the Sadguru gives birth to his disciple by granting full initiation (Anugraha) without any physical process. This spiritual birth is superior because it has the power to end the perpetual cycle of birth and death, a feat the text describes as extremely rare. The chapter elevates the Sadguru as the true father who removes the bondage of birth and death, acting as a "cloud of mercy" and a "light of knowledge" for the devotee.
