How does Chapter 6 describe the experience of non-duality (Advaita) and the manifestation of divine forms like Rama and Krishna through devotion to Sai?

Chapter 6 explains that devotion to Sai leads to profound spiritual experiences, including the realization of non-duality (Advaita). The text states that the Sadguru awakens the sense of 'I am He' (Soham) and reveals innate bliss, thereby dissolving the sense of 'me and mine'. This chapter also highlights how Sai manifests in other divine forms for His devotees. For instance, when a devotee reads scriptures or Puranas, Sai Himself takes the form of Rama and Krishna, making the devotee hear His own life story. It even describes how, while listening to the Bhagavat, Sai appears as Krishna from head to toe.
