Based on the Satcharitra, what is the unique role of a Sadguru compared to other fatherly figures?

Chapter 50 draws a powerful distinction between worldly fathers and the Sadguru. While it acknowledges the progenitor, the one who performs the thread ceremony, the protector, and the one who saves from fear, it states that the Sadguru is the true father. The text explains that a worldly father gives birth through a physical process, but a Sadguru is an extraordinary progenitor who gives spiritual birth to a disciple by granting initiation, or 'Anugraha.' This spiritual birth is considered superior because it has the power to end the endless cycle of birth and death, making the Sadguru the ultimate remover of this existential suffering.
