How does Chapter 50 differentiate between a worldly father and a Sadguru, and what makes the Sadguru an 'extraordinary progenitor'?

Chapter 50 draws a significant distinction between different types of fathers, elevating the Sadguru above all others. While a worldly father gives physical birth through the womb, the chapter describes the Sadguru as an 'extraordinary progenitor' who provides a spiritual birth. This rebirth is achieved not through a physical process but by granting full initiation, or 'Anugraha,' to the disciple. As stated in Chapter 50, this spiritual birth from the Guru is what ultimately has the power to end the cycle of physical birth and death, making the Sadguru the true father for a spiritual seeker.
