According to Chapter 27, what is the significance of surrendering to the Sadguru's feet and having faith?

Chapter 27 of the Sai Satcharitra explains that holding firmly to the feet of the Sadguru is of paramount importance, equating this act to bowing to the Trinity and saluting the Supreme Brahman. The text describes this surrender as taking a dip in an ocean that provides the merit of all pilgrimages. As mentioned in Chapter 27, without ultimate faith in the Guru's feet, the six passions like lust cannot be subsided, and supreme love and devotion will not emerge. To overcome the entanglement of Maya, the chapter advises that one must surrender to Sai with singular devotion, as this is the path to salvation.
