How does Chapter 50 describe the role and nature of a Sadguru in comparison to a worldly father?

Chapter 50 draws a profound distinction between a worldly father and a Sadguru. It explains that while a worldly father gives physical birth through the womb, a Sadguru provides a spiritual rebirth without any physical process. As stated in the chapter, the Sadguru is an "extraordinary progenitor" who, "without spending a drop of seed," gives birth to a disciple by granting full initiation, or Anugraha. This spiritual birth, as detailed in Chapter 50, is what ultimately helps a disciple end the cycle of birth and death, a feat the text describes as extremely rare. The chapter reveres the Sadguru as the "remover of birth and death" and the "light of knowledge."
