How does Chapter 50 differentiate between a worldly father and a Sadguru?

Chapter 50 draws a profound distinction between a worldly father and a Sadguru. While acknowledging the worldly father as the progenitor who gives physical birth, the text elevates the Sadguru to an 'extraordinary progenitor.' As explained in this chapter, the worldly father places a seed in the womb for physical birth, but the Sadguru gives a spiritual birth to the disciple without any physical process. He achieves this by granting full initiation (Anugraha), which has the power to end the cycle of birth and death. Therefore, the chapter posits that while one may have many parents across lifetimes, there is no truer father than a merciful Sadguru who can grant ultimate liberation.
