According to Chapter 50, how does a Sadguru's role as a 'progenitor' differ from that of a worldly father?

Chapter 50 draws a profound distinction between a worldly father and a Sadguru. While a worldly father gives physical birth through the womb, the Sadguru is described as an extraordinary progenitor who gives birth to a disciple in a spiritual sense. As detailed in the chapter, the Sadguru accomplishes this without any physical process, granting full initiation (Anugraha) to the disciple. This spiritual birth is considered superior because it has the power to end the cycle of birth and death, a feat the worldly father cannot achieve. Thus, the Sadguru is revered as the true father who removes the pains of birth and death.
