How does Chapter 6 illustrate that Sai Baba manifests as other deities for his devotees?

Chapter 6 of the Sai Satcharitra provides specific examples of how Sai Baba appears as other divine forms. The text states that when a devotee reads scriptures or Puranas, Sai Himself takes the form of Rama and Krishna to make them hear His own life story. It gives a specific instance where, while someone is listening to the Bhagavat, Sai appears as Krishna from head to toe, creating the feeling that He is personally singing the Uddhava Gita for the welfare of His devotees. This illustrates his ability to manifest in forms familiar and beloved to his followers.
