Can you explain how Chapter 6 illustrates the concept of non-duality (Advaita) and the devotee's experience of seeing Sai in other divine forms?

Chapter 6 explains that the Sadguru helps a devotee realize non-duality by awakening the sense of 'I am He' (Soham), which reveals innate bliss and dissolves the sense of 'me and mine.' This manifests the harmony of Advaita. The chapter provides examples of this phenomenon, stating that when a devotee reads scriptures or listens to stories like the Bhagavat, Sai Himself takes the form of Rama and Krishna, making the devotee hear His own life story. It is described so vividly that while listening to the Bhagavat, it feels as if Sai has appeared as Krishna from head to toe, singing the Uddhava Gita for his devotees.
