How does Chapter 50 of the Shri Sai Satcharitra describe the role and importance of a Sadguru?

Chapter 50 portrays the Sadguru as a figure of immense spiritual significance, far surpassing a worldly father. The text describes the Sadguru as an 'extraordinary progenitor' who, without any physical process, gives spiritual birth to a disciple through grace, thereby ending the cycle of birth and death. As detailed in this chapter, the Sadguru is the remover of this cycle, a cloud of mercy, and the light of knowledge. Furthermore, Chapter 50 states that Sai, as the Sadguru, is an embodiment of consciousness whose greatness is unfathomable and who has the power to crush a devotee's ego simply by placing his hand on their head.
