In what ways does Chapter 50 distinguish the role of a Sadguru from that of 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, the Sadguru is described as an 'extraordinary progenitor.' The chapter elaborates that a Sadguru gives a spiritual birth to his disciple through full initiation, or 'Anugraha', without any physical process. This spiritual birth, granted by the 'remover of birth and death,' is considered superior as it sets the disciple on the path to end the cycle of reincarnation, a feat the worldly father cannot accomplish. This unique role is highlighted as a wondrous miracle in the text.
