What is the relationship between the destruction of delusion discussed at the start of Chapter 51 and the role of a Sadguru?

Chapter 51 of the Sai Satcharitra establishes a direct relationship between a Sadguru's grace and the destruction of a disciple's delusion. It begins by analyzing the dialogue between Krishna and Arjuna, where the focus is on the vanishing of delusion ('moha'). Arjuna himself confirms, "By the words You have spoken, this delusion of mine has vanished." The chapter then transitions to its main narrative by stating that the grace of the Supreme Lord, earned through past merits, is what "leads to meeting the Sadguru." The implication, as presented in Chapter 51, is that the Sadguru, like Krishna for Arjuna, is the catalyst whose grace and teachings are essential for destroying the disciple's ignorance and delusion.
