Does Chapter 6 suggest that devotees saw Sai Baba as an incarnation of other deities like Rama and Krishna?

Yes, Chapter 6 explicitly describes how devotees experienced Sai Baba as manifestations of other prominent deities. The text notes that when a devotee reads scriptures or Puranas, the remembrance of the Sadguru is constant, and "Sai Himself takes the form of Rama and Krishna and makes one hear His own life story." This experience is further illustrated with a specific example. As recounted in Chapter 6, while a devotee was sitting to listen to the Bhagavat, "Sai appears as Krishna from head to toe; it feels as if He is singing the Uddhava Gita for the welfare of His devotees." This shows that devotees perceived Sai's divinity as encompassing and embodying these other revered forms.
