How does Chapter 50 of the Shri Sai Satcharitra distinguish between a worldly father and a Sadguru?

Chapter 50 draws a profound distinction between different types of fathers and the Sadguru. While it acknowledges the progenitor who gives life, the Guru who performs the thread ceremony, the provider of food, and the protector from fear, it elevates the Sadguru as the true father who can end the cycle of birth and death. The text explains this wonder by describing the Sadguru as an extraordinary progenitor. Unlike a worldly father, the Sadguru gives spiritual birth to his disciple by granting full initiation, or Anugraha, without any physical process, thus making the disciple his own spiritual son.
