According to Chapter 52, how does devotion to a Guru like Sai Baba lead to salvation and overcome delusion?

Chapter 52 teaches that those who wish to escape the cycle of birth and death should connect with the feet of the Guru through continuous remembrance and devotion. The text identifies delusion, or false knowledge which is the pride of the Self in that which is not the Self, as the root of all calamities. By dedicating oneself to Sai's devotion, one's salvation is assured. The chapter beautifully illustrates this by stating that just as a river forgets its river-ness upon embracing the ocean, a devotee who takes refuge in the Guru loses any sense of duality.
