I've heard Sai Baba is sometimes seen as other deities. Does Chapter 6 provide any examples of this?

Yes, Chapter 6 explicitly describes how Sai Baba manifests as other revered deities for His devotees. The text states that when a devotee reads scriptures or Puranas, they are constantly reminded of the Sadguru because "Sai Himself takes the form of Rama and Krishna and makes one hear His own life story." It provides a specific example, noting that while listening to the Bhagavat, a devotee might perceive Sai Baba as appearing "as Krishna from head to toe," feeling as if Baba Himself is singing the Uddhava Gita for their welfare. This shows how Baba's form is fluid and meets the devotee's devotional focus.
